Martin Atkins 39e609d5fd vendor: switch to HCL 2.0 in the HCL repository
Previously we were using the experimental HCL 2 repository, but now we'll
shift over to the v2 import path within the main HCL repository as part of
actually releasing HCL 2.0 as stable.

This is a mechanical search/replace to the new import paths. It also
switches to the v2.0.0 release of HCL, which includes some new code that
Terraform didn't previously have but should not change any behavior that
matters for Terraform's purposes.

For the moment the experimental HCL2 repository is still an indirect
dependency via terraform-config-inspect, so it remains in our go.sum and
vendor directories for the moment. Because terraform-config-inspect uses
a much smaller subset of the HCL2 functionality, this does still manage
to prune the vendor directory a little. A subsequent release of
terraform-config-inspect should allow us to completely remove that old
repository in a future commit.

Kristin Laemmert 06a3333316 note: this is an unusual edgecase in the category of "probably should not happen"
If https://github.com/hashicorp/terraform/issues/21543 is
fixed, we can remove this check.

Kristin Laemmert 703f024cbd command/show (-json): fix panic if a moduleCall has a nil config
In the unlikely event that a moduleCall has a nil config - for example,
if a nested module call includes a variable with a typo in an
attribute - continue gracefully.

Martin Atkins 88e76fa9ef configs/configschema: Introduce the NestingGroup mode for blocks
In study of existing providers we've found a pattern we werent previously
accounting for of using a nested block type to represent a group of
arguments that relate to a particular feature that is always enabled but
where it improves configuration readability to group all of its settings
together in a nested block.

The existing NestingSingle was not a good fit for this because it is
designed under the assumption that the presence or absence of the block
has some significance in enabling or disabling the relevant feature, and
so for these always-active cases we'd generate a misleading plan where
the settings for the feature appear totally absent, rather than showing
the default values that will be selected.

NestingGroup is, therefore, a slight variation of NestingSingle where
presence vs. absence of the block is not distinguishable (it's never null)
and instead its contents are treated as unset when the block is absent.
This then in turn causes any default values associated with the nested
arguments to be honored and displayed in the plan whenever the block is
not explicitly configured.

The current SDK cannot activate this mode, but that's okay because its
"legacy type system" opt-out flag allows it to force a block to be
processed in this way anyway. We're adding this now so that we can
introduce the feature in a future SDK without causing a breaking change
to the protocol, since the set of possible block nesting modes is not
extensible.

command/show: fixing bugs in modulecalls (#20513)
* command/show: fixing bugs in modulecalls

jsonconfig and jsonplan both had subtle bugs with the logic for
marshaling module calls that only showed up when multiple modules were
referenced. This PR fixes those bugs and extends the existing tests to
include multiple modules.

* sort all the things, mostly for tests

command/show enhancements and bugfixes
* command/jsonconfig: provider config marshaling enhancements

This PR fixes a bug wherein the keys in "provider_config" were the
"addrs.ProviderConfig", and therefore being overwritten for each module,
instead of the intended "addrs.AbsProviderConfig".

We realized that there was still opportunity for ambiguity, for example
if a user made a provider alias that was the same name as a module, so
we opted to use the syntax `modulename:providername(.provideralias)`

* command/json*: fixed a bug where we were attempting to lookup schemas
with the provider name, instead of provider type.

command/show: add "module_version" to "module_calls" in config (#20367)
* command/show: add "module_version" to "module_calls" in config portion
of `terraform show`.

Also extended the `terraform show -json` test to run `init` so we could
add examples with modules. This does _not_ test the "module_version"
yet, but it _did_ help expose a bug in jsonplan where modules were
duplicated. This is also fixed in this PR.

* command/jsonconfig: rename version to version_constraint and
resolved_source to source.

command/show: continued work on `terraform show -json` output (#20171)
* command/jsonstate: do not hide SchemaVersion of '0'
* command/jsonconfig: module_calls should be a map
* command/jsonplan: include current terraform version in output
* command/jsonconfig: properly marshal expressions from a module call

Previously this was looking at the root module's variables, instead of
the child module variables, to build the module schema. This fixes that
bug.

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.

command/show: tests for -json output (#19980)
* command/show: added test scaffold for json output

More test cases will be added once the basic shape of the tests is
validated.

- command/json* packages now sort resources by address, matching
behavior elsewhere
- using cmp in tests instead of reflect.DeepEqual for the diffs
- updating expected output in tests to match sorting

json output of terraform plan (#19687)
* command/show: adding functions to aid refactoring

The planfile -> statefile -> state logic path was getting hard to follow
with blurry human eyes. The getPlan... and getState... functions were
added to help streamline the logic flow. Continued refactoring may follow.

* command/show: use ctx.Config() instead of a config snapshot

As originally written, the jsonconfig marshaller was getting an error
when loading configs that included one or more modules. It's not clear
if that was an error in the function call or in the configloader itself,
  but as a simpler solution existed I did not dig too far.

* command/jsonplan: implement jsonplan.Marshal

Split the `config` portion into a discrete package to aid in naming
sanity (so we could have for example jsonconfig.Resource instead of
jsonplan.ConfigResource) and to enable marshaling the config on it's
own.
