Ceph set minimum client version
Ceph set minimum client version

This patch adds a new VAR for when the user wants to set the minimum
client version used in a Manila/Glance/Nova/Cinder test job in addition
to using devstack.

A new configuration option, CEPH_MIN_ CLIENT _VERSION, has been
introduced to specify a Ceph-minium client version that allows proper
handling when deleting images and snapshots with dependencies, etc. The
default value is null.
