Partially-Implements: blueprint one-data-container
All compose support in Kolla has been completely removed as of
liberty-3.
The files in this directory are only for reference by the TripleO
project. As they stand today, they likely don't work. There is a
blueprint to port them to support the CONFIG_EXTERNAL config
strategy.
