Martin Atkins 9a62ab3014 command: "terraform show" renders plans like "terraform plan"
During the Terraform 0.12 work we briefly had a partial update of the old
Terraform 0.11 (and prior) diff renderer that could work with the new
plan structure, but could produce only partial results.

We switched to the new plan implementation prior to release, but the
"terraform show" command was left calling into the old partial
implementation, and thus produced incomplete results when rendering a
saved plan.

Here we instead use the plan rendering logic from the "terraform plan"
command, making the output of both identical.

Unfortunately, due to the current backend architecture that logic lives
inside the local backend package, and it contains some business logic
around state and schema wrangling that would make it inappropriate to move
wholesale into the command/format package. To allow for a low-risk fix to
the "terraform show" output, here we avoid some more severe refactoring by
just exporting the rendering functionality in a way that allows the
"terraform show" command to call into it.

In future we'd like to move all of the code that actually writes to the
output into the "command" package so that the roles of these components
are better segregated, but that is too big a change to block fixing this
issue.

James Bardin e4640a43d7 fix show-json test to expect error from nested mod
One of the show json command tests expected no error when presented with
an invalid configuration in a nested module. Modify the test created in
PR #21569 so that it can still verify there is no panic, but now expect
an error from init.

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.

`terraform show` and `terraform providers schema -json` should return valid json (#20697)
* command/providers schemas: return empty json object if config parses successfully but no providers found
* command/show (state): return an empty object if state is nil

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: 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

Martin Atkins 7e186f72d9 command: Update "terraform show -json" tests for changed provider contract
We now require a provider to populate all of its defaults -- including
unknown value placeholders -- during PlanResourceChange. That means the
mock provider for testing "terraform show -json" must now manage the
population of the computed "id" attribute during plan.

To make this logic a little easier, we also change the ApplyResourceChange
implementation to fill in a non-null id, since that makes it easier for
the mock PlanResourceChange to recognize when it needs to populate that
default value during an update.

command/show: improvements to json output (#20139)

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.

Martin Atkins a3403f2766 terraform: Ugly huge change to weave in new State and Plan types
Due to how often the state and plan types are referenced throughout
Terraform, there isn't a great way to switch them out gradually. As a
consequence, this huge commit gets us from the old world to a _compilable_
new world, but still has a large number of known test failures due to
key functionality being stubbed out.

The stubs here are for anything that interacts with providers, since we
now need to do the follow-up work to similarly replace the old
terraform.ResourceProvider interface with its replacement in the new
"providers" package. That work, along with work to fix the remaining
failing tests, will follow in subsequent commits.

The aim here was to replace all references to terraform.State and its
downstream types with states.State, terraform.Plan with plans.Plan,
state.State with statemgr.State, and switch to the new implementations of
the state and plan file formats. However, due to the number of times those
types are used, this also ended up affecting numerous other parts of core
such as terraform.Hook, the backend.Backend interface, and most of the CLI
commands.

Just as with 5861dbf3fc49b19587a31816eb06f511ab861bb4 before, I apologize
in advance to the person who inevitably just found this huge commit while
spelunking through the commit history.

James Bardin e980156451 cleanup temp files from command tests
Rather than try to modify all the hundreds of calls to the temp helper
functions, and cleanup the temp files at every call site, have all tests
work within a single temp directory that is removed at the end of
TestMain.

Martin Atkins 8364383c35 Push plugin discovery down into command package
Previously we did plugin discovery in the main package, but as we move
towards versioned plugins we need more information available in order to
resolve plugins, so we move this responsibility into the command package
itself.

For the moment this is just preserving the existing behavior as long as
there are only internal and unversioned plugins present. This is the
final state for provisioners in 0.10, since we don't want to support
versioned provisioners yet. For providers this is just a checkpoint along
the way, since further work is required to apply version constraints from
configuration and support additional plugin search directories.

The automatic plugin discovery behavior is not desirable for tests because
we want to mock the plugins there, so we add a new backdoor for the tests
to use to skip the plugin discovery and just provide their own mock
implementations. Most of this diff is thus noisy rework of the tests to
use this new mechanism.
