CreateTag: Convert ConcurrentRefUpdateException into LockFailureException

Creating a tag may fail with a ConcurrentRefUpdateException that
represents a LOCK_FAILURE. Convert this exception into a
LockFailureException so that our auto-retrying logic for LOCK_FAILURES
can recognize the LOCK_FAILURE and retry the operation, instead of
failing immediately.

Example stacktrace:

Cannot create tag "refs/tags/foo-bar" [CONTEXT project="my-project" request="REST /projects/*/tags/*" ]
