Handle upgrading cinder-volume under pacemaker
Add upgrade tasks for cinder-volume when it's controlled by pacemaker:
o Stop the service before the entire pacemaker cluster is stopped.
This ensures the service is stopped before infrastructure services
(e.g. rabbitmq) go away.
o Migrate the cinder DB prior to restarting the service. This covers
the situation when puppet-cinder (who otherwise would handle the db
sync) isn't managing the service.
o Start the service after the rest of the pacemaker cluster has been
started.
