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)

Paul Hinze fbce3a3caa helper/resource: don't fail test on config warnings
AccTests like TestAccComputeInstance_basic_deprecated_network were
failing early on "invalid config" when we are explictly testing behavior
that we know generates warnings.

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.

Also clarified that final return value of testStep is now only for the
happy path.

Paul Hinze dbf6d1bd00 helper/resource: fix accidentaly swallowing of acctest step errors
With #1757 I unwittingly reused an err variable, causing all test check
errors to be swallowed. -_-

Paul Hinze 149e52ad1f helper/resource: verify refresh+plan after each step
I forgot to add `Computed: true` when I made the "key_name" field
optional in #1751.

This made the behavior:

 * Name generated in Create and set as ID
 * Follow up plan (without refresh) was nice and empty
 * During refresh, name gets cleared out on Read, causing a bad diff on
   subsequent plans

We can automatically catch bugs like this if we add yet another
verification step to our resource acceptance tests -> a post
Refresh+Plan that we verify is empty.

I left the non-refresh Plan verification in, because it's important that
_both_ of these are empty after an Apply.

Matt Good 21b0a03d70 Support for multiple providers of the same type
Adds an "alias" field to the provider which allows creating multiple instances
of a provider under different names. This provides support for configurations
such as multiple AWS providers for different regions. In each resource, the
provider can be set with the "provider" field.

(thanks to Cisco Cloud for their support)

Paul Hinze 7fe34d4547 providers: check for empty plan after each test step
Each acceptance test step plays a Refresh, Plan, Apply for a given
config. This adds a follow up Plan and fails the test if it does not
come back empty. This will catch issues with perpetual, unresolvable
diffs that crop up here and there.

This is going to cause a lot of our existing acceptance tests to fail -
too many to roll into a single PR. I think the best plan is to land this
in master and then fix the failures (each of which should be catching a
legitimate provider bug) one by one until we get the provider suites
back to green.

Paul Hinze 97acccd3ed core: targeted operations
Add `-target=resource` flag to core operations, allowing users to
target specific resources in their infrastructure. When `-target` is
used, the operation will only apply to that resource and its
dependencies.

The calculated dependencies are different depending on whether we're
running a normal operation or a `terraform destroy`.

Generally, "dependencies" refers to ancestors: resources falling
_before_ the target in the graph, because their changes are required to
accurately act on the target.

For destroys, "dependencies" are descendents: those resources which fall
_after_ the target. These resources depend on our target, which is going
to be destroyed, so they should also be destroyed.
