In some deployments, after an upgrade, we remove the old service
records and create new ones. This leaves the volumes with the
service_uuid pointing to the old (deleted) service and causes an
issue while purging out the deleted service records.
This patch adds a cinder-manage command to update the
service_uuid field of volumes with the following command:
``cinder-manage volume update_service``
The service_uuid of volumes associated with old service_uuid
also gets updated when cinder creates a new service.
