    Add hooks to workaround patching bugs

    Add several pre and post patching hooks and tests
    for them.

    * Stop or migrate corosync services from controller node
      and return them after the deployment

    * Stop openstack services and kill pids that was
      not stopped together with their children

    * Remove openstack packages before deployment
      to prevent conflicts during the update and rollback
