Add support for RBD fast-diff feature for backups stored in Ceph
This change enables the FAST_DIFF feature for backup images stored
via Ceph RBD. It is enabled together with EXCLUSIVE_LOCK and
OBJECT_MAP as required.
With FAST_DIFF enabled, the generation of diffs between images and
snapshots as well as determining the actual data usage of a snapshot
is sped up significantly.
