config: JSON resource keys with only one item load properly GH-5140
When a resource has only a single key set, the HCL parser treats that
key as part of the overall set of object keys. This isn't valid since
we expect resources to have exactly two keys. In this scenario, we have
to "unwrap" the keys back into a set of objects.

James Bardin 8dcbc0b0a0 Add concat to accept lists of lists and maps
This will allow the concat interpolation function to accept lists of
lists, and lists of maps as well as strings. We still allow bare strings
for backwards compatibility, but remove some of the old comment wording
as it could cause confusion of this function with actual string
concatenation.

Since maps are now supported in the config, this removes the superfluous
(and failing) TestInterpolationFuncConcatListOfMaps.

James Nugent 58dd41f3b1 core: Add list() interpolation function
The list() interpolation function provides a way to add support for list
literals (of strings) to HIL without having to invent new syntax for it
and modify the HIL parser.

It presents as a function, thus:

    - list() -> []
    - list("a") -> ["a"]
    - list("a", "b") -> ["a", "b"]

Thanks to @wr0ngway for the idea of this approach, fixes #7460.

James Nugent c6e03cba96 core: Fix slice element keys on interpolateWalk
Part of the interpolation walk is to detect keys which involve computed
values and therefore cannot be resolved at this time. The interplation
walker keeps sufficient state to be able to populate the ResourceConfig
with a slice of such keys.

Previously they didn't take slice indexes into account, so in the
following case:

```
"services": []interface{}{
    map[string]interface{}{
        "elb": "___something computed___",
    },
    map[string]interface{}{
        "elb": "___something else computed___",
    },
    map[string]interface{}{
        "elb": "not computed",
    },
}
```

Unknown keys would be populated as follows:

```
services.elb
services.elb
```

This is not sufficient information to be useful, as it is impossible to
distinguish which of the `services.elb`s are unknown vs not.

This commit therefore retains the slice indexes as part of the key for
unknown keys - producing for the example above:

```
services.0.elb
services.1.elb
```

Dot indexing worked in the "regexps and strings" world of 0.6.x, but it

There is plenty of dot-indexed config out in the wild, so we need to do

also need to address Resource Variables and Module Variables in a

James Nugent cb9ef298f3 core: Defeat backward compatibilty in mapstructure
The mapstructure library has a regrettable backward compatibility
concern whereby a WeakDecode of []interface{}{} into a target of
map[string]interface{} yields an empty map rather than an error. One
possibility is to switch to using Decode instead of WeakDecode, but this
loses the nice handling of type conversion, requiring a large volume of
code to be added to Terraform or HIL in order to retain that behaviour.

Instead we add a DecodeHook to our usage of the mapstructure library
which checks for decoding []interface{}{} or []string{} into a map and
returns an error instead.

This has the effect of defeating the code added to retain backwards
compatibility in mapstructure, giving us the correct (for our
circumstances) behaviour of Decode for empty structures and the type
conversion of WeakDecode.

The code is identical to that in the HIL library, and packaged into a
helper.

Martin Atkins 60c24e3319 command: Prevent data resources from being tainted
Since the data resource lifecycle contains no steps to deal with tainted
instances, we must make sure that they never get created.

Doing this out in the command layer is not the best, but this is currently
the only layer that has enough information to make this decision and so
this simple solution was preferred over a more disruptive refactoring,
under the assumption that this taint functionality eventually gets
reworked in terms of StateFilter anyway.

Martin Atkins fc4fa10981 config: "ResourceMode" concept for resources
Previously resources were assumed to always support the full set of
create, read, update and delete operations, and Terraform's resource
management lifecycle.

Data sources introduce a new kind of resource that only supports the
"read" operation. To support this, a new "Mode" field is added to
the Resource concept within the config layer, which can be set to
ManagedResourceMode (to indicate the only mode previously possible) or
DataResourceMode (to indicate that only "read" is supported).

To support both managed and data resources in the tests, the
stringification of resources in config_string.go is adjusted slightly
to use the Id() method rather than the unusual type[name] serialization
from before, causing a simple mechanical adjustment to the loader tests'
expected result strings.

James Nugent f49583d25a core: support native list variables in config
This commit adds support for native list variables and outputs, building
up on the previous change to state. Interpolation functions now return
native lists in preference to StringList.

List variables are defined like this:

variable "test" {
    # This can also be inferred
    type = "list"
    default = ["Hello", "World"]
}

output "test_out" {
    value = "${var.a_list}"
}
This results in the following state:

```
...
            "outputs": {
                "test_out": [
                    "hello",
                    "world"
                ]
            },
...
```

And the result of terraform output is as follows:

```
$ terraform output
test_out = [
  hello
  world
]
```

Using the output name, an xargs-friendly representation is output:

```
$ terraform output test_out
hello
world
```

The output command also supports indexing into the list (with
appropriate range checking and no wrapping):

```
$ terraform output test_out 1
world
```

Along with maps, list outputs from one module may be passed as variables
into another, removing the need for the `join(",", var.list_as_string)`
and `split(",", var.list_as_string)` which was previously necessary in
Terraform configuration.

This commit also updates the tests and implementations of built-in
interpolation functions to take and return native lists where
appropriate.

A backwards compatibility note: previously the concat interpolation
function was capable of concatenating either strings or lists. The
strings use case was deprectated a long time ago but still remained.
Because we cannot return `ast.TypeAny` from an interpolation function,
this use case is no longer supported for strings - `concat` is only
capable of concatenating lists. This should not be a huge issue - the
type checker picks up incorrect parameters, and the native HIL string
concatenation - or the `join` function - can be used to replicate the
missing behaviour.

James Nugent e57a399d71 core: Use native HIL maps instead of flatmaps
This changes the representation of maps in the interpolator from the
dotted flatmap form of a string variable named "var.variablename.key"
per map element to use native HIL maps instead.

This involves porting some of the interpolation functions in order to
keep the tests green, and adding support for map outputs.

There is one backwards incompatibility: as a result of an implementation
detail of maps, one could access an indexed map variable using the
syntax "${var.variablename.key}".

This is no longer possible - instead HIL native syntax -
"${var.variablename["key"]}" must be used. This was previously
documented, (though not heavily used) so it must be noted as a backward
compatibility issue for Terraform 0.7.

James Nugent b62f6af158 core: Add support for marking outputs as sensitive (#6559)
* core: Add support for marking outputs as sensitive

This commit allows an output to be marked "sensitive", in which case the
value is redacted in the post-refresh and post-apply list of outputs.

For example, the configuration:

```
variable "input" {
    default = "Hello world"
}

output "notsensitive" {
    value = "${var.input}"
}

output "sensitive" {
    sensitive = true
    value = "${var.input}"
}
```

Would result in the output:

```
terraform apply

Apply complete! Resources: 0 added, 0 changed, 0 destroyed.

Outputs:

  notsensitive = Hello world
  sensitive    = <sensitive>
```

The `terraform output` command continues to display the value as before.

Limitations: Note that sensitivity is not tracked internally, so if the
output is interpolated in another module into a resource, the value will
be displayed. The value is still present in the state.

James Nugent d7d39702c0 Type check variables between modules (#6185)
These tests demonstrates a problem where the types to a module input are 
not checked. For example, if a module - inner - defines a variable
"should_be_a_map" as a map, or with a default variable of map, we do not
fail if the user sets the variable value in the outer module to a string
value. This is also a problem in nested modules.

The implementation changes add a type checking step into the graph
evaluation process to ensure invalid types are not passed.

Paul Hinze 3f72837f4b core: Make copies when creating destroy nodes
Fixes an interpolation race that was occurring when a tainted destroy
node and a primary destroy node both tried to interpolate a computed
count in their config. Since they were sharing a pointer to the _same_
config, depending on how the race played out one of them could catch the
config uninterpolated and would then throw a syntax error.

The `Copy()` tree implemented for this fix can probably be used
elsewhere - basically we should copy the config whenever we drop nodes
into the graph - but for now I'm just applying it to the place that
fixes this bug.

Fixes #4982 - Includes a test covering that race condition.

James Nugent cb6cb8b96a core: Support explicit variable type declaration
This commit adds support for declaring variable types in Terraform
configuration. Historically, the type has been inferred from the default
value, defaulting to string if no default was supplied. This has caused
users to devise workarounds if they wanted to declare a map but provide
values from a .tfvars file (for example).

The new syntax adds the "type" key to variable blocks:

```
variable "i_am_a_string" {
    type = "string"
}

variable "i_am_a_map" {
    type = "map"
}
```

This commit does _not_ extend the type system to include bools, integers
or floats - the only two types available are maps and strings.

Validation is performed if a default value is provided in order to
ensure that the default value type matches the declared type.

In the case that a type is not declared, the old logic is used for
determining the type. This allows backwards compatiblity with previous
Terraform configuration.

Paul Hinze 0739cf2348 provider/template: fix race causing panic in template_file
The render code path in `template_file` was doing unsynchronized access
to a shared mapping of functions in `config.Func`.

This caused a race condition that was most often triggered when a
`template_file` had a `count` of more than one, and expressed itself as
a panic in the plugin followed by a cascade of "unexpected EOF" errors
through the plugin system.

Here, we simply turn the FuncMap from shared state into a generated
value, which avoids the race. We do more re-initialization of the data
structure, but the performance implications are minimal, and we can
always revisit with a perf pass later now that the race is fixed.

James Nugent 5ea25363a1 Add regression test for #4069
This may be brittle as it makes use of .gitattributes to override the
autocrlf setting in order to have an input file with Windows line
endings across multiple platforms.

Paul Hinze 15e7927009 config: test covering escaped quotes syntax error
This was never intended to be valid syntax, but it worked in the old HCL
parser, and we've found a decent number of examples of it in the wild.

Fixed in https://github.com/hashicorp/hcl/pull/62 and we'll keep this
test in Terraform to cover the behavior.

Paul Hinze 928f534cfc template_file: source contents instead of path
Building on the work of #3846, deprecate `filename` in favor of a
`template` attribute that accepts file contents instead of a path.

Required a bit of work in the interpolation code to prevent Terraform
from assuming that template interpolations were resource variables that
needed to be resolved. Leaving them as "Unknown Variables" prevents
interpolation from happening early and lets the `template_file` resource
do its thing.

James Nugent f4164b5322 Add resource with heredoc to config load tests
This test reproduces the issue which is likely the root cause of #3840.
Test is currently failing with an "illegal character" message
corresponding with the location of the heredoc, which is also seen in
various acceptance tests for providers.
