deprecations:

  - Option ``memcached_servers`` is deprecated in Mitaka. Operators should
    use oslo.cache configuration instead. Specifically ``enabled`` option
    under [cache] section should be set to True, the ``backend`` option to
    ``oslo_cache.memcache_pool`` and the location(s) of the
    memcached servers should be in [cache]/memcache_servers option.
