Disable openstack-cinder-volume in step1 and reenable it in step2

Currently we do not disable openstack-cinder-volume during our
major-upgrade-pacemaker step. This leads to the following scenario. In
major_upgrade_controller_pacemaker_2.sh we do:

  start_or_enable_service galera
  check_resource galera started 600
  ....
  if [[ -n $(is_bootstrap_node) ]]; then
  ...
      cinder-manage db sync
  ...

What happens here is that since openstack-cinder-volume was never
disabled it will already be started by pacemaker before we call
cinder-manage and this will give us the following errors during the
start:
06:05:21.861 19482 ERROR cinder.cmd.volume DBError:
                   (pymysql.err.InternalError) (1054, u"Unknown column 'services.cluster_name' in 'field list'")
