command/show: improvements to json output (#20139)
* command/show: add support for -json output for state

* command/jsonconfig: do not marshal empty count/for each expressions

* command/jsonstate: continue gracefully if the terraform version is somehow missing from state

* 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.

Martin Atkins a270a18a4d command: Update tests for changes in "terraform" package
This is not exhaustive, but it gets the tests in this package compiling
again and gets most of them working.

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.
