James Nugent 7b6df27e4a helper/schema: Read native maps from configuration
This adds a test and the support necessary to read from native maps
passed as variables via interpolation - for example:

```
resource ...... {
     mapValue = "${var.map}"
}
```

We also add support for interpolating maps from the flat-mapped resource
config, which is necessary to support assignment of computed maps, which
is now valid.

Unfortunately there is no good way to distinguish between a list and a
map in the flatmap. In lieu of changing that representation (which is
risky), we assume that if all the keys are numeric, this is intended to
be a list, and if not it is intended to be a map. This does preclude
maps which have purely numeric keys, which should be noted as a
backwards compatibility concern.

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.

Mitchell Hashimoto 35c87836b4 core: Add terraform_version to state
This adds a field terraform_version to the state that represents the
Terraform version that wrote that state. If Terraform encounters a state
written by a future version, it will error. You must use at least the
version that wrote that state.

Internally we have fields to override this behavior (StateFutureAllowed),
but I chose not to expose them as CLI flags, since the user can just
modify the state directly. This is tricky, but should be tricky to
represent the horrible disaster that can happen by enabling it.

We didn't have to bump the state format version since the absense of the
field means it was written by version "0.0.0" which will always be
older. In effect though this change will always apply to version 2 of
the state since it appears in 0.7 which bumped the version for other
purposes.

helper/schema: Normalize bools to "true"/"false" in diffs
For a long time now, the diff logic has relied on the behavior of
`mapstructure.WeakDecode` to determine how various primitives are
converted into strings.  The `schema.DiffString` function is used for
all primitive field types: TypeBool, TypeInt, TypeFloat, and TypeString.

The `mapstructure` library's string representation of booleans is "0"
and "1", which differs from `strconv.FormatBool`'s "false" and "true"
(which is used in writing out boolean fields to the state).

Because of this difference, diffs have long had the potential for
cosmetically odd but semantically neutral output like:

    "true" => "1"
    "false" => "0"

So long as `mapstructure.Decode` or `strconv.ParseBool` are used to
interpret these strings, there's no functional problem.

We had our first clear functional problem with #6005 and friends, where
users noticed diffs like the above showing up unexpectedly and causing
troubles when `ignore_changes` was in play.

This particular bug occurs down in Terraform core's EvalIgnoreChanges.
There, the diff is modified to account for ignored attributes, and
special logic attempts to handle properly the situation where the
ignored attribute was going to trigger a resource replacement. That
logic relies on the string representations of the Old and New fields in
the diff to be the same so that it filters properly.

So therefore, we now get a bug when a diff includes `Old: "0", New:
"false"` since the strings do not match, and `ignore_changes` is not
properly handled.

Here, we introduce `TypeBool`-specific normalizing into `finalizeDiff`.
I spiked out a full `diffBool` function, but figuring out which pieces
of `diffString` to duplicate there got hairy. This seemed like a simpler
and more direct solution.

Fixes #6005 (and potentially others!)

helper/resource: make id-only check opt-in
As I've been working through the resources, I'm finding that a lot are
going to need some serious work. Given we have hundreds, I think it
might be prudent to make this opt-in for now and we can revisit
automatic/opt-out at some future point.

Importability will likely be opt-in it appears so this will match up
with that.

helper/resource: use the full config for id-only checks
Originally I used an empty config module. This caused problems since
important provider configurations weren't available. Instead, I now set
it to use the full config. This isn't an issue since the attributes
themselves aren't available to Refresh anyways.

Paul Hinze c3e27b3e0a provider/test: a test provider
Here we also introduce a `test` provider meant as an aid to exposing
via automated tests issues involving interactions between
`helper/schema` and Terraform core.

This has been helpful so far in diagnosing `ignore_changes` problems,
and I imagine it will be helpful in other contexts as well.

We'll have to be careful to prevent the `test` provider from becoming a
dumping ground for poorly specified tests that have a clear home
elsewhere. But for bug exposure I think it's useful to have.

Paul Hinze 108ccf0007 builtin: Refactor resource.Retry to clarify return
Change the `RetryFunc` from a plain `error` return type to a
specialized `RetryError` which must decide whether it is
retryable or not.

Add `RetryableError` / `NonRetryableError` factory functions that
callers are meant to use to build up these errors.

This makes it eminently clear whether or not a given error is
retryable from inside the client code.

Goal here is to _not_ change any behavior, simply reflect the
existing behavior with the new, clearer, API.

Paul Hinze 5160578e18 helper/resource: restore retval of resource.Retry on timeout
In #4700 while fixing a data race I made an incorrect assumption about
the return value of StateChangeConf, and ended up changing the behavior
in the timeout case to always return:

> timeout while waiting for state to become '[success]'

When it used to capture the "most recent error" from the function
itself.

It's much more useful to see that error bubbling up, so here we revert
to pulling it out of the function as we did before, and we protect
against the data race with a good old fashioned mutex.

Paul Hinze c70eab6500 aws: undeprecate min_elb_capacity; restore min capacity waiting
It was a mistake to switched fully to `==` when activating waiting for
capacity on updates in #3947. Users that didn't set `min_elb_capacity ==
desired_capacity` and instead treated it as an actual "minimum" would
see timeouts for every create, since their target numbers would never be
reached exactly.

Here, we fix that regression by restoring the minimum waiting behavior
during creates.

In order to preserve all the stated behavior, I had to split out
different criteria for create and update, criteria which are now
exhaustively unit tested.

The set of fields that affect capacity waiting behavior has become a bit
of a mess. Next major release I'd like to rework all of these into a
more consistently named block of config. For now, just getting the
behavior correct and documented.

(Also removes all the fixed names from the ASG tests as I was hitting
collision issues running them over here.)

Paul Hinze 069425a700 consul: Fix several problems w/ consul_keys update
Implementation notes:

 * The hash implementation was not considering key value, causing "diffs
   did not match" errors when a value was updated. Switching to default
   HashResource implementation fixes this
 * Using HashResource as a default exposed a bug in helper/schema that
   needed to be fixed so the Set function is picked up properly during
   Read
 * Stop writing back values into the `key` attribute; it triggers extra
   diffs when `default` is used. Computed values all just go into `var`.
 * Includes a state migration to prevent unnecessary diffs based on
   "key" attribute hashcodes changing.

In the tests:

 * Switch from leaning on the public demo Consul instance to requiring a
   CONSUL_HTTP_ADDR variable be set pointing to a `consul agent -dev`
   instance to be used only for testing.
 * Add a test that exposes the updating issues and covers the fixes
