[rdo-list] [tripleo][ci] oooq role changes

FYI, Per some discussion in the RDO-CI meeting today I have very quickly created some launchpad bugs to track some changes for tripleo-quickstart. I plan on updating the bugs w/ more details but there should be enough there to start the conversation. Replace oooq inventory w/ external role: https://bugs.launchpad.net/tripleo-quickstart/+bug/1604517 Remove overcloud deployment from oooq native and use external role https://bugs.launchpad.net/tripleo-quickstart/+bug/1604518 Remove overcloud validation from oooq native and use external role https://bugs.launchpad.net/tripleo-quickstart/+bug/1604520 Thanks
