Fix DevStack Ceph on the Giant release

Browse Source 
As of the Ceph Giant release, pools 'data' and 'metadata' (used for
CephFS) were removed. Thus applying the pool change command fails on
Giant since those pools don't exist anymore. Now we are checking for
every release prior to Giant and apply proper commands accordingly.
