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 33ba6774e0 Make the state commands use the real command.Meta
In order to use a backend for the state commands, we need an initialized
meta. Use a single Meta instance rather than temporary ones to make sure
the backends are initialized properly.

Martin Atkins fee1197cf9 command: terraform state rm to require at least one argument
Due to how the state filter machinery works, passing no arguments is valid
and matches _all_ resources.

It is very unlikely that someone wants to remove everything from state, so
this ends up being a very dangerous default for the "terraform state rm"
command, and surprising for someone who perhaps runs it looking for the
usage information.

So we'll be pragmatic here and reject the no-arguments case for this
command, accepting that it makes the unlikely case of intentionally
deleting all resources harder in order to make it less likely that it
will happen _unintentionally_.

If someone does really want to remove all resources from the state, they
can provide an explicit empty string argument, but this isn't documented
because it's a weird case that doesn't seem worth mentioning.

This fixes #15283.

James Bardin 6e7baaaeff don't load the backend when -state is provided
When using a `state` command, if the `-state` flag is provided we do not
want to modify the Backend state. In this case we should always create a
local state instance.

The backup flag was also being ignored, and some tests were relying on
that, which have been fixed.

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.

command/state: mv and rm -backup works
Fixes #12154

The "-backup" flag before for "state *" CLI had some REALLY bizarre behavior:
it would change the _destination_ state and actually not create any
additional backup at all (the original state was unchanged and the
normal timestamped backup still are written). Really weird.

This PR makes the -backup flag work as you'd expect with one caveat:
we'll _still_ create the timestamped backup file. The timestamped backup
file helps make sure that you always get a backup history when using
these commands. We don't want to make it easy for you to overwrite a
state with the `-backup` flag.

Mitchell Hashimoto 3fdc08a9eb core: Add `terraform state rm` command and docs
This commit adds the `state rm` command for removing an address from
state. It is the result of a rebase from pull-request #5953 which was
lost at some point during the Terraform 0.7 feature branch merges.
