Martin Atkins 8f27409007 backend/remote: Support HCL variable values in local operations
For remote operations, the remote system (Terraform Cloud or Enterprise)
writes the stored variable values into a .tfvars file before running the
remote copy of Terraform CLI.

By contrast, for operations that only run locally (like
"terraform import"), we fetch the stored variable values from the remote
API and add them into the set of available variables directly as part
of creating the local execution context.

Previously in the local-only case we were assuming that all stored
variables are strings, which isn't true: the Terraform Cloud/Enterprise UI
allows users to specify that a particular variable is given as an HCL
expression, in which case the correct behavior is to parse and evaluate
the expression to obtain the final value.

This also addresses a related issue whereby previously we were forcing
all sensitive values to be represented as a special string "<sensitive>".
That leads to type checking errors for any variable specified as having
a type other than string, so instead here we use an unknown value as a
placeholder so that type checking can pass.

Unpopulated sensitive values may cause errors downstream though, so we'll
also produce a warning for each of them to let the user know that those
variables are not available for local-only operations. It's a warning
rather than an error so that operations that don't rely on known values
for those variables can potentially complete successfully.

This can potentially produce errors in situations that would've been
silently ignored before: if a remote variable is marked as being HCL
syntax but is not valid HCL then it will now fail parsing at this early
stage, whereas previously it would've just passed through as a string
and failed only if the operation tried to interpret it as a non-string.
However, in situations like these the remote operations like
"terraform plan" would already have been failing with an equivalent
error message anyway, so it's unlikely that any existing workspace that
is being used for routine operations would have such a broken
configuration.

Martin Atkins 9f9f22091e backend/remote: Unlock workspace if Context fails
Previously any error case in the Context method would cause us to leave
the remote workspace locked on exit, requiring manual action to unlock it.

Martin Atkins b10f058cbb backend/remote: Only load variables if we're going to use them
Some commands don't use variables at all or use them in a way that doesn't
require them to all be fully valid and consistent. For those, we don't
want to fetch variable values from the remote system and try to validate
them because that's wasteful and likely to cause unnecessary error
messages.

Furthermore, the variables endpoint in Terraform Cloud and Enterprise only
works for personal access tokens, so it's important that we don't assume
we can _always_ use it. If we do, then we'll see problems when commands
are run inside Terraform Cloud and Enterprise remote execution contexts,
where the variables map always comes back as empty.

Martin Atkins a8d01e3940 backend/remote: Report invalid variables only remotely
The remote backend uses backend.ParseVariableValues locally only to decide
if the user seems to be trying to use -var or -var-file options locally,
since those are not supported for the remote backend.

Other than detecting those, we don't actually have any need to use the
results of backend.ParseVariableValues, and so it's better for us to
ignore any errors it produces itself and prefer to just send a
potentially-invalid request to the remote system and let the remote system
be responsible for validating it.

This then avoids issues caused by the fact that when remote operations are
in use the local system does not have all of the required context: it
can't see which environment variables will be set in the remote execution
context nor which variables the remote system will set using its own
generated -var-file based on the workspace stored variables.

cost estimation status polling
Properly wait for cost estimation to finish running before outputting
the results. Waits 500 milliseconds between checks, rather than backing
off exponentially, because we are not in a run queue. At the point we're
waiting, we expect cost estimation to be run in a timely manner.

backend/remote: remove milseading contents from error message (#22148)
Previously, terraform was returning a potentially-misleading error
message in response to anything other than a 404 from the
b.client.Workspaces.Read operation. This PR simplifies Terraform's error
message with the intent of encouraging those who encounter it to focus
on the error message returned from the tfe client.

The added test is odd, and a bit hacky, and possibly overkill.

Kristin Laemmert 190ef537ec backend/remote: notify users when uploading something other than cwd
When a TFC workspace is configured without a VCS root, and with a
working directory, and a user is running `terraform init` from that same
directory, TFC uploads the entire configuration directory, not only the
user's cwd. This is not obvious to the user, so we are adding a descriptive
message explaining what is being uploaded, and why.

[WIP] backend/enhanced: start with absolute configuration path (#22096)
* backend/enhanced: start with absolute config path

We recently started normalizing the config path before all "command"
operations, which was necessary for consistency but had unexpected
consequences for remote backend operations, specifically when a vcs root
with a working directory are configured.

This PR de-normalizes the path back to an absolute path.

* Check the error and add a test

It turned out all required logic was already present, so I just needed to add a test for this specific use case.

Sander van Harmelen 394f20f59c backend/remote: do not unlock after a failed upload
When changes are made and we failed to upload the state, we should not
try to unlock the workspace. Leaving the workspace locked is a good
indication something went wrong and also prevents other changes from
being applied before the newest state is properly uploaded.

Additionally we now output the lock ID when a lock or force-unlock
action failed.

Sander van Harmelen 54736b068b backend/remote: use `state.v2` for remote state only
The API surface area is much smaller when we use the remote backend for remote state only.

So in order to try and prevent any backwards incompatibilities when TF runs inside of TFE, we’ve split up the discovery services into `state.v2` (which can be used for remote state only configurations, so when running in TFE) and `tfe.v2.1` (which can be used for all remote configurations).
