Code Issues Proposed changes

Add support for multiple Cinder RBD backends

Browse Source 
Add new CinderRbdExtraPools Heat parameter, 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.

Adding this feature requires changes in two areas:
o The extra Cinder RBD backends get created via a new Puppet parameter
o The Ceph client key that permits access to specific Ceph pools is
  updated to allow client access to the extra RBD pools

Add new CinderRbdExtraPools Heat parameter, 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.
