If there were no matching keys, and there was no diff at all, don't set
a zero count for the container. Normally Providers can't reliably detect
empty vs unset here, but there are some cases that worked.

Martin Atkins c70954aeab tools/terraform-bundle: refuse to bundle versions <0.12.0
Since terraform-bundle is just a different frontend to Terraform's module
installer, it is subject to the same installation constraints as Terraform
itself.

Terraform 0.12 cannot install providers targeting Terraform 0.11 and
earlier, and so therefore terraform-bundle built with Terraform 0.12
cannot either. A build of terraform-bundle from the v0.11 line must be
used instead.

Without this change, the latest revisions of terraform-bundle would
install plugins for Terraform 0.12 to bundle along with Terraform 0.10 or
0.11, which will not work at runtime due to the plugin protocol mismatch.

Until now, terraform-bundle was incorrectly labelled with its own version
number even though in practice it has no version identity separate from
Terraform itself. Part of this change, then, is to make the
terraform-bundle version match the Terraform version it was built against,
though any prior builds will of course continue to refer to themselves
as 0.0.1.

If asked to create a bundle for a version of Terraform v0.12 or greater,
an error will be returned instructing the user to use a build from the
v0.11 branch or one of the v0.11.x tags in order to bundle those versions.

This also includes a small fix for a bug where the tool would not fail
properly when the requested Terraform version is not available for
installation, instead just producing a zip file with no "terraform"
executable inside at all. Now it will fail, allowing automated build
processes to detect it and not produce a broken archive for distribution.

mildwonkey/b-show-state (#20032)
* command/show: properly marshal attribute values to json

marshalAttributeValues in jsonstate and jsonplan packages was returning
a cty.Value, which json/encoding could not marshal. These functions now
convert those cty.Values into json.RawMessages.

* command/jsonplan: planned values should include resources that are not changing
* command/jsonplan: return a filtered list of proposed 'after' attributes

Previously, proposed 'after' attributes were not being shown if the
attributes were not WhollyKnown. jsonplan now iterates through all the
`after` attributes, omitting those which are not wholly known.

The same was roughly true for after_unknown, and that structure is now
correctly populated. In the future we may choose to filter the
after_unknown structure to _only_ display unknown attributes, instead of
all attributes.

* command/jsonconfig: use a unique key for providers so that aliased
providers don't get munged together

This now uses the same "provider" key from configs.Module, e.g.
`providername.provideralias`.

* command/jsonplan: unknownAsBool needs to iterate through objects that are not wholly known

* command/jsonplan: properly display actions as strings according to the RFC,
instead of a plans.Action string.

For example:
a plans.Action string DeleteThenCreate should be displayed as ["delete",
"create"]

Tests have been updated to reflect this.

* command/jsonplan: return "null" for unknown list items.

The length of a list could be meaningful on its own, so we will turn
unknowns into "null". The same is less likely true for maps and objects,
so we will continue to omit unknown values from those.

Martin Atkins 995042666a config/hcl2shim: ValuesSDKEquivalent float64 comparison of numbers
The SDK uses only the native int and float64 types internally for values
that are specified as being "number" in schema, so for SDK purposes only
a float64 level of precision is significant.

To avoid any weirdness introduced as we shim and un-shim numbers, we'll
reduce floating point numbers to float64 precision before comparing them
to try to mimic the result the SDK itself would've gotten from comparing
its own float64 versions of these values using the Go "==" operator.

Martin Atkins f65b7c5372 helper/plugin: Discard meaningless differences from provider planning
Due to various inprecisions in the old SDK implementation, applying the
generated diff can potentially make changes to the data structure that
have no real effect, such as replacing an empty list with a null list or
vice-versa.

Although we can't totally eliminate such diff noise, here we attempt to
avoid it in situations where there are _only_ meaningless changes -- where
the prior state and planned state are equivalent -- by just echoing back
the prior state verbatim to ensure that Terraform will treat it as a noop
change.

If there _are_ some legitimate changes then the result may still contain
meaningless changes alongside it, but that is just a cosmetic problem for
the diff renderer, because the meaningless changes will be ignored
altogether during a subsequent apply anyway. The primary goal here is just
to ensure we can converge on a fixpoint when there are no explicit changes
in the configuration.

Martin Atkins 6b03c81375 config/hcl2shim: ValuesSDKEquivalent function
This is a first pass of an "approximately equal" function that tries to
mimic the reduced precision caused by the field reader abstraction in
helper/schema so that we can distinguish between meaningful changes to
the proposed new state and incidental ones that just result from the loss
of precision in the SDK implementation.

James Bardin 7257258f18 new Diff.Apply
The previous version assumed the diff could be applied verbatim, and
only used the schema at the top level since diffs are "flat". This
turned out to not work reliably with nested blocks. The new Apply method
is driven completely by the schema, and handles nested blocks separately
from other collections.

Martin Atkins 10bf4c763b backend: Undeclared variables in -var-file is a warning, not an error
In Terraform 0.11 and earlier we just silently ignored undeclared
variables in -var-file and the automatically-loaded .tfvars files. This
was a bad user experience for anyone who made a typo in a variable name
and got no feedback about it, so we made this an error for 0.12.

However, several users are now relying on the silent-ignore behavior for
automation scenarios where they pass the same .tfvars file to all
configurations in their organization and expect Terraform to ignore any
settings that are not relevant to a specific configuration. We never
intentionally supported that, but we don't want to immediately break that
workflow during 0.12 upgrade.

As a compromise, then, we'll make this a warning for v0.12.0 that contains
a deprecation notice suggesting to move to using environment variables
for this "cross-configuration variables" use-case. We don't produce errors
for undeclared variables in environment variables, even though that
potentially causes the same UX annoyance as ignoring them in vars files,
because environment variables are assumed to live in the user's session
and this it would be very inconvenient to have to unset such variables
when moving between directories. Their "ambientness" makes them a better
fit for these automatically-assigned general variable values that may or
may not be used by a particular configuration.

This can revert to being an error in a future major release, after users
have had the opportunity to migrate their automation solutions over to
use environment variables.

We don't seem to have any tests covering this specific situation right
now. That isn't ideal, but this change is so straightforward that it would
be relatively expensive to build new targeted test cases for it and so
I instead just hand-tested that it is indeed now producing a warning where
we were previously producing an error. Hopefully if there is any more
substantial work done on this codepath in future that will be our prompt
to add some unit tests for this.

Martin Atkins 15cd6d8300 core: Retain prior state if update fails with no new state
In an ideal world, providers are supposed to respond to errors during
apply by returning a partial new state alongside the error diagnostics.
In practice though, our SDK leaves the new value set to nil for certain
errors, which was causing Terraform to "forget" the object altogether by
assuming that the provider intended to say "null".

We now adjust that assumption to apply only in the delete case. In all
other cases (including updates) we retain the prior state if the new
state is given as nil. Although we could potentially fix this in the SDK
itself, I expect this is a likely bug in other future SDKs for other
languages too, so this new assumption is a safer one to make to be
resilient to data loss when providers don't behave perfectly.

Providers that return both nil new value and no errors are considered
buggy, but unfortunately that applies to the mocks in many of our tests,
so for pragmatic reasons we can't generate an error for that case as we do
for other "should never happen" situations. Instead, we'll just retain the
prior value in the state so the user can retry.

Martin Atkins 8b094f48f7 command: Update "terraform get" to use the new module installer
We missed this on the initial update pass because this was calling
directly into the module package API rather than going through the Meta
methods that we updated for the new config loader.

m.installModules here is the same method that "terraform init" is using
for this purpose, ensuring the two will behave the same way. This changes
the output a little compared to the old installer, but it still includes
the important information about where each module is coming from.

Martin Atkins 176a5abfd3 command: Restore single-file support in "terraform fmt"
This possibility was lost in the rewrite to use HCL2, but it's used by
a number of external utilities and text editor integrations, so we'll
restore it here.

Using the stdin/stdout mode is generally preferable for text editor use
since it allows formatting of the in-memory buffer rather than directly
the file on disk, but for editors that don't have support for that sort of
tooling it can be convenient to just launch a single command and directly
modify the on-disk file.
