[Rdo-list] RDO-Manager liberty CI is green!

We have automated CI passing against liberty based RDO-Manager.[1] The CI follows the upstream tripleo docs[2] with only one undocumented step for this documentation bug[3]. The HA job does not look like it will pass, but it is not 100% stable upstream[4]. Besides HA, we need the following: - Document the network isolation feature on liberty and get some job using that feature. - Get a promote job working that runs a packstack job as well as RDO-Manager job(s) and promotes based on all green (promotion is still manual) - Find a place to host images for the current-passed-ci repo to reduce the runtime on gate jobs. Huge props to weshay and dmsimard for helping get this going. --trown
