librbd: add new lock_get_owners / lock_break_lock API methods

If the client application supports failover, let the application
force break the current lock and blacklist the owner. This is
required in case the current lock owner is alive from the point-of-view
of librbd but failover was required due to a higher level reason.

ceph_volume_client: check if volume metadata is empty

... when recovering from partial auth updates.

Auth update happens in the following order:
auth metadata update, volume metadata update, and then Ceph auth
update.

A partial auth update can happen such that auth metadata is updated,
but the volume metadata isn't updated and is empty, and the auth
update did not propogate to Ceph. When recovering from such a
scenario, check if volume metadata is empty and if so remove the
partial auth update info in auth metadata.

qa/tasks/workunit: clear clone dir before retrying checkout

If we checkout ceph-ci.git, and don't find a branch,
we'll try again from ceph.git. But the checkout will
already exist and the clone will fail, so we'll still
fail to find the branch.

The same can happen if a previous workunit task already
checked out the repo.

Fix by removing the repo before checkout (the first and
second times).  Note that this may break if there are
multiple workunit tasks running in parallel on the same
role.  That is already racy, so if it's happening, we'll
want to switch to using a truly unique clonedir for each
instantiation.
