    Adds a standardised method to configure notifications for different
    services.
deprecations:

    The ``enable_cadf_notifications`` variable is deprecated. CADF is the
    default notification format in keystone. To enable keystone notifications,
    users should now set ``keystone_default_notifications_topic_enabled`` to
    ``yes`` or enable Ceilometer via ``enable_ceilometer``.
