Add rbd secret_uuid in secondary config

Browse Source 
- Update initialize_connection to return active
backend connection data.
- Add secret_uuid support in secondary config

  For example:
  replication_device = backend_id:secondary,
                       conf:/etc/ceph/secondary.conf,
                       user:SECONDARY_UDER,
                       secret_uuid:SENDARY_SECRET_UUID

Rbd replication secondary device could set different user and keyring with primary cluster.
Secondary secret_uuid value is configed in libvirt secret, and libvirtd using secondary secret
reconnect to secondary cluster after Cinder failover host.
