upgrade:
  - |
    ``cinder-volume`` and ``cinder-backup`` containers are now
    deployed by default on ``cinder`` group - which effectively
    is ``control`` by default (earlier it defaulted to ``storage``).
  - |
    New Ansible inventory groups have been introduced to support properly
    Cinder LVM backend setup:

    * ``cinder-backup-lvm``
    * ``cinder-backup-multiple``
    * ``cinder-volume-lvm``
    * ``cinder-volume-multiple``

    Please update your inventory overrides accordingly.
