Today for some services we mount in /var/lib/config-data/<service>/etc
which is actually an output from the container-puppet process. We should
be using kolla to ensure that we properly create the configurations
based on the puppet generated configurations and things in the
container. Some services correctly leverage the kolla_config that the
associated api/service uses when running their db sync. This patch
aligns the rest to follow the similar pattern.
