This commit replaces func returns with t.Cleanup,
which makes API and tests slightly easier to maintain.

Allows backend snapshots to bring existing snapshots into
a namespace without requiring clients to fully snapshots
when the target reference is known. Backend snapshots must
explicitly implement this functionality, it is equivalent
to sharing across namespaces and is up to the backend to
use the label when it is given or ignore it.
This enables remote snapshot functionality for a backend to
query for a target snapshot before a client has performed
any work to create that snapshot.

Updates metadata plugin to require content and
snapshotter plugins be loaded and initializes with
those plugins, keeping the metadata database structure
static after initialization. Service plugins now only
require metadata plugin access snapshotter or content
stores through metadata, which was already required
behavior of the services.

The testsuite alters global state by setting the umask, avoid
running the testsuite in parallel and move umask manipulation
to the test suite level to individual tests may run in parallel.
Added better error messaging and handling.
Removed reliance on testing object for handling cleanup failure.
When a cleanup error occurred, it would fail the test but the log
would get skipped. With this change the failure will show up for
the running test.
Update test unmounting to set the detach flag, avoiding races with
btrfs which may see the device as busy when attempting to unmount.

The snapshot test suite is designed to run against the snapshotter
interface, run the test suite for metadata and client implementations
of the snapshotter interface.
