Chris Marchesi fa1fc2ca8e helper/schema: CustomizeDiff invocation test
Just one more test to check to make sure that CustomizeDiff is called
on resource level.

Chris Marchesi 8af9610b87 helper/schema: Hook CustomizeDiffFunc into diff logic
It's alive! CustomizeDiff logic now has been inserted into the diff
process. The test_resource_with_custom_diff resource provides some basic
testing and a reference implementation.

There should now be plenty of test coverage for this feature via the
tests added for ResourceDiff, and the basic test added to the
schemaMap.Diff test, and the test resource, but more can be added to
test any specific case that comes up otherwise.

Clint 3fdeacdca7 helper/schema: Rename Timeout resource block to Timeouts (#12533)
helper/schema: Rename Timeout resource block to Timeouts

- Pluralize configuration argument name to better represent that there is
one block for many timeouts
- use a const for the configuration timeouts key
- update docs

Clint 2fe5976aec helper/schema: Add configurable Timeouts (#12311)
* helper/schema: Add custom Timeout block for resources

* refactor DefaultTimeout to suuport multiple types. Load meta in Refresh from Instance State

* update vpc but it probably wont last anyway

* refactor test into table test for more cases

* rename constant keys

* refactor configdecode

* remove VPC demo

* remove comments

* remove more comments

* refactor some

* rename timeKeys to timeoutKeys

* remove note

* documentation/resources: Document the Timeout block

* document timeouts

* have a test case that covers 'hours'

* restore a System default timeout of 20 minutes, instead of 0

* restore system default timeout of 20 minutes, refactor tests, add test method to handle system default

* rename timeout key constants

* test applying timeout to state

* refactor test

* Add resource Diff test

* clarify docs

* update to use constants

terraform: InstanceState.Meta is value type interface{}
This changes the type of values in Meta for InstanceState to
`interface{}`. They were `string` before.

This will allow richer structures to be persisted to this without
flatmapping them (down with flatmap!). The documentation clearly states
that only primitives/collections are allowed here.

The only thing using this was helper/schema for schema versioning.
Appropriate type checking was added to make this change safe.

The timeout work @catsby is doing will use this for a richer structure.

James Nugent 074545e536 core: Use .% instead of .# for maps in state
The flatmapped representation of state prior to this commit encoded maps
and lists (and therefore by extension, sets) with a key corresponding to
the number of elements, or the unknown variable indicator under a .# key
and then individual items. For example, the list ["a", "b", "c"] would
have been encoded as:

    listname.# = 3
    listname.0 = "a"
    listname.1 = "b"
    listname.2 = "c"

And the map {"key1": "value1", "key2", "value2"} would have been encoded
as:

    mapname.# = 2
    mapname.key1 = "value1"
    mapname.key2 = "value2"

Sets use the hash code as the key - for example a set with a (fictional)
hashcode calculation may look like:

    setname.# = 2
    setname.12312512 = "value1"
    setname.56345233 = "value2"

Prior to the work done to extend the type system, this was sufficient
since the internal representation of these was effectively the same.
However, following the separation of maps and lists into distinct
first-class types, this encoding presents a problem: given a state file,
it is impossible to tell the encoding of an empty list and an empty map
apart. This presents problems for the type checker during interpolation,
as many interpolation functions will operate on only one of these two
structures.

This commit therefore changes the representation in state of maps to use
a "%" as the key for the number of elements. Consequently the map above
will now be encoded as:

    mapname.% = 2
    mapname.key1 = "value1"
    mapname.key2 = "value2"

This has the effect of an empty list (or set) now being encoded as:

    listname.# = 0

And an empty map now being encoded as:

    mapname.% = 0

Therefore we can eliminate some nasty guessing logic from the resource
variable supplier for interpolation, at the cost of having to migrate
state up front (to follow in a subsequent commit).

In order to reduce the number of potential situations in which resources
would be "forced new", we continue to accept "#" as the count key when
reading maps via helper/schema. There is no situation under which we can
allow "#" as an actual map key in any case, as it would not be
distinguishable from a list or set in state.

Martin Atkins 6a468dcd83 helper/schema: Resource can be writable or not
In the "schema" layer a Resource is just any "thing" that has a schema
and supports some or all of the CRUD operations. Data sources introduce
a new use of Resource to represent read-only resources, which require
some different InternalValidate logic.

Paul Hinze 7eb72e7a12 helper/schema: record schema version when destroy fails
This was just a missed exit from the resource.Apply function -
subsequent refreshes would add the SchemaVersion back into the state,
but having the state recorded once without the meta information can
cause problems with Atlas's remote state checksumming.

Paul Hinze 3ba8ed536b helper/schema: record schema version on apply
We were previously only recording the schema version on refresh. This
caused the state to be incorrectly written after a `terraform apply`
causing subsequent commands to run the state through an unnecessary
migration.

Paul Hinze 3d4b55e557 helper/schema: schema versioning & migration
Providers get a per-resource SchemaVersion integer that they can bump
when a resource's schema changes format. Each InstanceState with an
older recorded SchemaVersion than the cureent one is yielded to a
`MigrateSchema` function to be transformed such that it can be addressed
by the current version of the resource's Schema.
