addrs: replace "Type string" with "Type Provider" in ProviderConfig
* huge change to weave new addrs.Provider into addrs.ProviderConfig
* terraform: do not include an empty string in the returned Providers /
Provisioners
- Fixed a minor bug where results included an extra empty string

command/show (json): marshal the state snapshot included with the plan file (#21597)
* command/show: marshal the state snapshot from the planfile

The planfile contains a state snapshot with certain resources updated
(outputs and datasources). Previously `terraform show -json PLANFILE`
was using the current state instead of the state inside the plan as
intended.

This caused an issue when the state included a terraform_remote_state
datasource. The datasource's state gets refreshed - and therefore
upgraded to the current state version - during plan, but that won't
persist to state until apply.

* update comment to reflect new return

command/show (plan -json): fix panic (#21541)
* command/show -json: fix panic

afterUnknown should return only bools, not values.

* command/jsonplan: let's delete some redundant code!

the plan output was somewhat inconsistent with return values for
"after_unknown". This strives to fix that. If all "after" values are
known, return an empty object instead of iterating over values.

Also fixing some typos and general copypasta.

Martin Atkins d512584497 command/jsonplan: Don't panic with mixtures of known/unknown/empty
The omitUnknowns and unknownAsBool functions were previously trying hard
to preserve the same collection types in the output as they had in the
input, by attempting to keep everything matched up so that the results
would be valid.

Unfortunately, this turns out to be a harder problem than we originally
thought: it was possible for a collection value going in to produce
inconsistent element types out (and thus a panic) in the following
situations:
- when a collection with mixed known and unknown values was passed in
  to omitUnknowns.
- when a collection of collections where the inner collections are a
  mixture of empty and not empty in unknownAsNull.

The results of these functions are only used to marshal to JSON anyway,
and JSON serialization can't distinguish between the three sequence types
or the two mapping types, so in practice we can just standardize on
converting all sequences to tuple and all mappings to object here and not
change the resulting output at all, and then we don't have to worry about
making sure all of the inner types get preserved exactly.

A nice consequence of that relaxation is that we can now do what we
originally wanted to do with unknownAsBool, and omit map keys and
object attributes altogether if their values would've been false,
producing a much more compact result. This is easiest to do now when
there's only one known user of this JSON plan output, and we know that
user will treat both false and omitted as the same here.

command/show: differentiate between state schemas and plan schemas. (#20516)
When a planfile is supplied to the `terraform show -json` command, the
context that loads only included schemas for resources in the plan. We
found an edge case where removing a data source from the configuration
(though only if there are no managed resources from the same provider)
would cause jsonstate.Marshal to fail because the provider schema wasn't
in the plan context.

jsonplan.Marshal now takes two schemas, one for plan and one for state.
If the state schema is nil it will simply use the plan schemas.

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: json output enhancements (#20291)
* command/jsonplan: 
- add variables to plan output
- print known planned values for resources

Previously, resource attribute values were only displayed if the values
were wholly known. Now we will filter the unknown values out of the
change and print the known values.

* command/jsonstate: added depends_on and tainted fields
* command/show: update tests to reflect added fields

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.
