Post following bellow is just proof of concept that packstack might be used for RDO Ocata deployment using the same current-passed-ci delorean Ocata Trunk as it does on regular basis TripleO QuickStart. I am not doing multinode set up due to known limitation of packstack, e.g. disability split controller and storage nodes either on bare metal or in virtual environment. Looks like it mostly serves as part of the testing pipeline that promotes trunk repositories to "current-passed-ci".
