Docker compute role configured via Puppet
This change adds a containerized version of the overcloud compute node for TripleO. Configuration files are generated via OpenStack Puppet modules which are then used to externally configure kolla containers for each OpenStack service. See the README-containers.md file for more information on how to set this up. This uses AtomicOS as a base operating system and requires that we bootstrap the image with a container which contains the required os-collect-config agent hooks to support running puppet, shell scripts, and docker compose.
