Description Ram Raja 2018-07-11 11:03:07 UTC 
Description of problem:
Need to expose APIs to enable manila's cephfs driver to atomically update RADOS objects. Implement 'put_object_versioned()' and 'get_object_and_version()' methods in ceph_volume_client to allow the manila driver to do so.

You can run the following test in the qa suite to verify that the new method work,
