Container-puppet (former docker-puppet) tool does not synchronize removed config files

[Bogdan Dobrelya]

T-h-t common/container-puppet.py tool only propagates config files removed by puppet to /var/lib/config-data/${NAME} (where NAME is the config-volume name of a service). But those do not end up being removed in the /var/lib/config-data/puppet-generated/${NAME} immediately. While it must be.

This creates situations, when potentially conflicting configurations, like loaded Apache MPM modules, may co-exist. Kolla extended start picks it up later and might fail, when it bootstraps the main service $NAME container.
