The first step is landing the nodepool elements in nodepool.rdoproject.org, and
building a centos-7 DIB.  I believe number80 is currently working on this and
hopefully that could be landed in the next day or so.  Once images have been
built, it won't be much work to then run a job. RDO already has 3rdparty jobs
running, we'd to the same with tripleo-ci.
