A new CinderRbdExtraPools Heat parameter has been added, which specifies a list of Ceph pools for use with RBD backends for Cinder. An extra Cinder RBD backend driver is created for each pool in the list. This is in addition to the standard RBD backend driver associated with the CinderRbdPoolName. The new parameter is optional, and defaults to an empty list. All of the pools are associated with a single Ceph cluster.
