Alan Bishop e2936d7604 Add cinder RBD support for multiple ceph clusters
The CinderRbdMultiConfig parameter provides a mechanism for
configuring cinder RBD backends associated with external ceph
clusters defined by CephExternalMultiConfig.

A new nova_libvirt_init_secret.sh script handles the creation of
the libvirt secret that is required for nova to connect to volumes
on the cinder RBD backends.
