RBD driver `bug #1907964
<https://bugs.launchpad.net/cinder/+bug/1907964>`_: Add support
for fast-diff on backup images stored in Ceph.
Provided fast-diff is supported by the backend it will automatically be
enabled and used.
With fast-diff enabled, the generation of diffs between images and
snapshots as well as determining the actual data usage of a snapshot
is speed up significantly.
