James Bardin 5be15ed77c have the local backend provide a plugin init msg
During plan and apply, because the provider constraints need to be built
from a plan, they are not checked until the terraform.Context is
created. Since the context is always requested by the backend during the
Operation, the backend needs to be responsible for generating contextual
error messages for the user.

Instead of formatting the ResolveProviders errors during NewContext,
return a special error type, ResourceProviderError to signal that
init will be required. The backend can then extract and format the
errors.

Chris Marchesi f249386c8a core: Test to ensure PostDiff is ignoring stubs

Chris Marchesi 45528b2217 core: Instance/EvalDiff.Quiet -> Stub
Changed the language of this field to indicate that this diff is not a
"real" diff, in that it should not be acted on, versus a "quiet" mode,
which would indicate just simply to act silently.

Chris Marchesi eef933f2a7 core: Don't count scaled-out resources twice in the UI
This fixes a bug with the new refresh graph behaviour where a resource
was being counted twice in the UI on part of being scaled out:

 * We are no longer transforming refresh nodes without state to
   plannable resources (the transformer will be removed shortly)
 * A Quiet flag has been added to EvalDiff and InstanceDiff - this
   allows for the flagging of a diff that should not be treated as real
   diff for purposes of planning
 * When there is no state for a refresh node now, a new path is taken
   that is similar to plan, but flags Quiet, and does nothing with the
   diff afterwards.

Tests pending - light testing has confirmed this should fix the double
count issue, but we should have some tests to actually confirm the bug.

Martin Atkins 418a8a8bc9 command + backend: rename various API objects to "Workspace" terminology
We're shifting terminology from "environment" to "workspace". This takes
care of some of the main internal API surface that was using the old
terminology, though is not intended to be entirely comprehensive and is
mainly just to minimize the amount of confusion for maintainers as we
continue moving towards eliminating the old terminology.

David Glasser c25d848ffb core: allow overriding environment name via env var
This allows you to run multiple concurrent terraform operations against
different environments from the same source directory.

Fixes #14447.

Also removes some dead code which appears to do the same thing as the function I
modified.

Martin Atkins c835ef8ff3 Update tests for the new ProviderResolver interface
Rather than providing an already-resolved map of plugins to core, we now
provide a "provider resolver" which knows how to resolve a set of provider
dependencies, to be determined later, and produce that map.

This requires the context to be instantiated in a different way, so this
very noisy diff is a mostly-mechanical update of all of the existing
places where contexts get created for testing, using some adapted versions
of the pre-existing utilities for passing in mock providers.

Martin Atkins a42ebe389c Revert "have StateHook periodically PersistState"
This reverts commit b73d037761.

This commit seems to have introduced a race condition where we can
concurrently keep updating state after we've checked if we need to
increase the serial, and thus end up writing partial changes
to the state backend.

In the case of Terraform Enterprise, this fails altogether because
of the state hash consistency check it does.

James Bardin 9e4c0ff2ad call PersistState immediately when cancelling
When the backend operation is cancelled, immediately call PersistState.
The is a high likelihood that the user is going to terminate the process
early if the provider doesn't return in a timely manner, so persist as
much state as possible.

Martin Atkins 9cda37205d backend/local: create local state file if backend write fails
In the old remote state system we had the idea of a local backup, which
is actually still present for the legacy backends but no longer applies
for the new-style backends like the s3 backend.

It's problematic when an apply runs for long enough that someone's
time-limited AWS STS credentials expire and then Terraform fails and can't
persist state to S3.

To reduce the risk of lost state, here we add some extra fallback code
for the local apply operation in particular. If either state writing
or state persisting fail then we attempt to write the state to a special
backup file errored.tfstate, and produce an error message that guides the
user on how to retry uploading this state.

In the unlikely event that we can't write to local disk either (e.g.
permissions problems) we take a last-ditch attempt to dump the JSON onto
stdout and advise the user to manually copy it into a file for import.
If even that doesn't work for some reason, we assume a critical Terraform
bug (JSON-serialization problem with states?) and bail out with an
apologetic error message.

This is implemented for the apply command in particular because this is
the one command where new objects are created in real APIs that we don't
want to lose track of. For other operations it's less bad to just generate
a simple error message and have the user retry.

This fixes #14298.

James Bardin 928e60672f context Refresh and Apply sometimes return nil
The documentation for Refresh indicates that it will always return a
valid state, but that wasn't true in the case of a graph builder error.
While this same concept wasn't documented for Apply, it was still
assumed in the terraform apply code.

Since the helper testing framework relies on the absence of a state to
determine if it can call Destroy, the Context can't can't start
returning a state in all cases. Document this, and use the State method
to fetch the correct state value after Apply.

Add a nil check to the WriteState function, so that writing a nil state
is a noop.

Make sure to init before sorting the state, to make sure we're not
attempting to sort nil values. This isn't technically needed with the
current code, but it's just safer in general.

command: remove legacy remote state on migration
Fixes #12871

We were forgetting to remove the legacy remote state from the actual
state value when migrating. This only causes an issue when saving a plan
since the plan contains the state itself and causes an error where both
a backend + legacy state exist.

If saved plans aren't used this causes no noticable issue.

Due to buggy upgrades already existing in the wild, I also added code to
clear the remote section if it exists in a standard unchanged backend

backend/local: allow refresh on empty/non-existent state
This allows a refresh on a non-existent or empty state file. We changed
this in 0.9.0 to error which seemed reasonable but it turns out this
complicates automation that runs refresh since it now needed to
determine if the state file was empty before running.

Its easier to just revert this into a warning with exit code zero.

The reason this changed is because in 0.8.x and earlier, the output
would be simply empty with exit code zero which seemed odd.

backend/local: refresh with no config should not crash on input
Fixes #12174

You're allowed to refresh with a nil module (no configs) as long as you
have state. However, if `-input=true` (default) then this would crash
since the input attempts to read the configs.

The API contract with `terraform.Context` says that the module tree must
be non-nil and loaded. To do this for other commands we create an empty
module tree. We do that here now.
