Until now the default workspace for every project would have the ID 1,
which would make it impossible to lock them at the same time since we
use the ID to identify the lock. With a global sequence to generate the
IDs, the default workspace will now have a different ID for each project
and it will be possible to lock multiple unrelated projects at the same
time.
If an old version of Terraform tries to get the lock on a project created
with this new version it will work as we continue to use the ID of the
workspace, we just change the way we generate them.
If this version tries to get a lock on a project created by an old
version of Terraform it will work as usual, but we may encounter a
conflict with another unrelated project. This is already the current
behavior so it's not an issue to persist this behavior. As users migrate
to an up-to-date version of Terraform this will stop.
Projects already present in the database will keep their conflicting IDs,
I did not wanted to change them as users may be reading the states
directly in the database for some reason. They can if they want change
them manually to remove conflicts, newly created projects will work
without manual intervention.

Use a single log writer instance for all std library logging.
Setup the std log writer in the logging package, and remove boilerplate
from test packages.
pathorcontents was solely used by the gcs backend. I moved the function
into the backend package so it could still be used by other backends for
good measure.
* remove unused code
I've removed the provider-specific code under registry, and unused nil
backend, and replaced a call to helper from backend/oss (the other
callers of that func are provisioners scheduled to be deprecated).
I also removed the Dockerfile, as our build process uses a different
file.
Finally I removed the examples directory, which had outdated examples
and links. There are better, actively maintained examples available.
* command: remove various unused bits
* test wasn't running
* backend: remove unused err
The Consul KV store limits the size of the values in the KV store to 524288
bytes. Once the state reaches this limit Consul will refuse to save it. It is
currently possible to try to bypass this limitation by enable Gzip but the issue
will manifest itself later. This is particularly inconvenient as it is possible
for the state to reach this limit without changing the Terraform configuration
as datasources or computed attributes can suddenly return more data than they
used to. Several users already had issues with this.
To fix the problem once and for all we now split the payload in chunks of 524288
bytes when they are to large and store them separatly in the KV store. A small
JSON payload that references all the chunks so we can retrieve them later and
concatenate them to reconstruct the payload.
While this has the caveat of requiring multiple calls to Consul that cannot be
done as a single transaction as those have the same size limit, we use unique
paths for the chunks and CAS when setting the last payload so possible issues
during calls to Put() should not result in unreadable states.

When the path ends with / (e.g. `path = "tfstate/"), the lock
path used will contain two consecutive slashes (e.g. `tfstate//.lock`) which
Consul does not accept.
This change the lock path so it is sanitized to `tfstate/.lock`.
If the user has two different Terraform project, one with `path = "tfstate"` and
the other with `path = "tfstate/"`, the paths for the locks will be the same
which will be confusing as locking one project will lock both. I wish it were
possible to forbid ending slashes altogether but doing so would require all
users currently having an ending slash in the path to manually move their
Terraform state and would be a poor user experience.

When locking was enabled with the Consul backend and the lock not properly
released, the `terraform force-unlock <lock_id>` command would do nothing as
its implementation would exit early in that case.
It now destroys the session that created the lock and clean both the lock and
the lock-info keys.
A regression test is added to TestConsul_destroyLock() to catch the issue if it
happends again.

Most of the state package has been deprecated by the states package.
This PR replaces all the references to the old state package that
can be done simply - the low-hanging fruit.
* states: move state.Locker to statemgr
The state.Locker interface was a wrapper around a statemgr.Full, so
moving this was relatively straightforward.
* command: remove unnecessary use of state package for writing local terraform state files
* move state.LocalState into terraform package
state.LocalState is responsible for managing terraform.States, so it
made sense (to me) to move it into the terraform package.
* slight change of heart: move state.LocalState into clistate instead of
terraform
* Azure backend: support snapshots/versioning
