    Set memcached server to local one for non-keyston services

    We misconfigured local cache for services with change
    https://review.openstack.org/#/q/Id1034e22d79c3ea6b25575d9bcf8e8750a02365d
    Thus, it becomes extremely slow when a controller is down.

    With this commit we revert things back to normal with local memcached
    for all openstack services leaving keystone memcached shared for tokens
    (this was thoroughly tested previously)

    This commit https://github.com/openstack/fuel-library/commit/a529033fdcb36ccea8cf0cc76339816ed31418c7
    pointed all non-keystone services to local memcached for keystone auth tokens, however it also
    pointed cache/memcache_servers in nova to local memcached. This led to regression in Nova.

    Revert setting local memcached server for swift proxy

    Switch back to using all available mamcached servers, because of
    failures during swift testing.
