Gorka Eguileor f91b29cd0c Support A/A in delete actions and get_capabilities
This patch allows deleting operations and getting capabilities in HA
Active-Active configurations.

To allow this we have to use the cluster topic queue in the Message
Broker, so following RPC methods in cinder/volume/rpcapi have been
changed:

- delete_volume
- delete_snapshot
- delete_consistencygroup
- delete_cgsnapshot
- delete_group
- delete_group_snapshot

When the cluster field is not set all RPC calls will behave as before,
sending it to the host topic queue.

Everything in Cinder's release notes related to the High Availability
Active-Active effort -preluded with "HA A-A:"- is work in progress and
should not be used in production until it has been completed and the
appropriate release note has been issued stating its readiness for
production.
features:
- "HA A-A: Add cluster configuration option to allow grouping hosts that
share the same backend configurations and should work in Active-Active
fashion."
- "HA A-A: Updated manage command to display cluster information on service
listings."
- "HA A-A: Added cluster subcommand in manage command to list, remove, and
rename clusters."
- "HA A-A: Added clusters API endpoints for cluster related operations (index,
detail, show, enable/disable). Index and detail accept filtering by
`name`, `binary`, `disabled`, `num_hosts`, `num_down_hosts`, and up/down
status (`is_up`) as URL parameters. Also added their respective policies."
- "HA A-A: Attach and detach operations are now cluster aware and make full
use of clustered cinder-volume services."
- "HA A-A: Delete volume, delete snapshot, delete consistency group, and
delete consistency group snapshot operations are now cluster aware and make
full use of clustered cinder-volume services."
