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.

Simon Thulbourn 33d2afc26d Add headers to output
The original implmentation was missing headers to denote mime version &
content transfer encoding, this caused issues with EC2.

James Nugent abffa67a49 Rename resource.go -> resource_template_file.go
This is necessitated by new resources being added to the template
provider.

James Nugent a926fa6fdd Adds template_cloudinit_config resource to template
This adds a new resource to template to generate multipart cloudinit
configurations to be used with other providers/resources.

The resource has the ability gzip and base64 encode the parts.

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.

Paul Hinze 385b17d679 provider/template: don't error when rendering fails in Exists
The Exists function can run in a context where the contents of the
template have changed, but it uses the old set of variables from the
state. This means that when the set of variables changes, rendering will
fail in Exists. This was returning an error, but really it just needs to
be treated as a scenario where the template needs re-rendering.

fixes #2344 and possibly a few other template issues floating around

Paul Hinze 06eb388c3f provider/template: store relative path in state
This makes template_file usage in modules portable.

Paul Hinze a96a3372c6 provider/template: don't diff when there's no diff
This reworks the template lifecycle a bit such that we get nicer diff
behavior.

First, we tick ForceNew on for both filename and vars, so that the diff
indicates that the template will be "replaced" on change. This is mostly
cosmetic, but it also tracks conceptually with the fact that the
identifier we use is a hash of the contents, so any change essentially
makes a "new resource".

Second, we change the Exists implementation to only return `false` when
there has been a change in the rendered template. This lets descendent
resources see the computed value changing so that they'll properly
trigger in the plan.

Fixes #1898
Refs #1866 (but does not fix, there's another deeper issue there)

Josh Bleecher Snyder 76bcac3031 providers/template: add tests, address review comments
Do directory expansion on filenames.

Add basic acceptance tests. Code coverage is 72.5%.
Uncovered code is uninteresting and/or impossible error cases.

Note that this required adding a knob to
helper/resource.TestStep to allow transient
resources.
