Also:
- In the getting started guide, the TFE content was all tailored to the older
run-locally workflow. I've replaced it with some brief explanation and a link
to the dedicated TFE getting started guide.
- Fixed a sidebar link glitch in the configuration section. (Both "Terraform"
and "Terraform Enterprise" were marked as active if you were on the TFE page.)
- Renamed the "Terraform Enterprise" page "Terraform Push." (Some people have
gotten confused and landed on this page when trying to set up the `atlas`
remote backend.)
Use the new StateLocker field to provide a wrapper for locking the state
during terraform.Context creation in the commands that directly
manipulate the state.
Simplify the use of clistate.Lock by creating a clistate.Locker
instance, which stores the context of locking a state, to allow unlock
to be called without knowledge of how the state was locked.
This alows the backend code to bring the needed UI methods to the point
where the state is locked, and still unlock the state from an outer
scope.
Provide a NoopLocker as well, so that callers can always call Unlock
without verifying the status of the lock.
Add the StateLocker field to the backend.Operation, so that the state
lock can be carried between the different function scopes of the backend
code. This will allow the backend context to lock the state before it's
read, while allowing the different operations to unlock the state when
they complete.
Use the new StateLocker field to provide a wrapper for locking the state

Use the new StateLocker field to provide a wrapper for locking the state
during terraform.Context creation. We can then remove all the state
locking code from individual operations, and unlock them in one place
inside the main Operation method.

backend context to lock the state before it's read, while allowing the

The test target will already cover vet, since it's run as part of the
test command now.
Also remove the `go test -i` since it's no longer needed with the new
build cache.
Fix the now failing state unlock test by reporting the correct ID.
The ID used by GCS is the generation number of the info object, which
isn't known until the info is already written out. While we can't get
the correct ID from the info data for the error rmessage, we can update
it with the generation number after it's read.
This adds a general test to verify that a remote state backend returns
the expected error type when it cannot lock a state. It then extracts
the ID reported in the error, and attempts to unlock the state using
that ID, which simulated the force-unlock scenario. This is a separate
test, since not all backends have persistent locks that can be unlocked
later.
We also split out the backend test to be called individually as needed.
This new argument allows overriding of the working directory of the child process, with the default still being the working directory of Terraform itself.
This is rarely needed, but sometimes tests need to create temporary files as part of their operation. This should be used sparingly, since it prevents the pro-active cleanup of the temporary working directory.
