This was a goal for tripleo-test-cloud-rh2, to move that to thirdparty CI,
ensure jobs work, then migrated. As you can see, we never actually did that.

My preference would be to make the move the thirdparty now, with
tripleo-test-cloud-rh1.  We now have all the pieces in place for RDO project to
support this and in parallel set up RDO cloud to run jobs from RDO.

If RDO stablility is a concern, the move to thirdparty first seems to make the
most sense. This avoid the need to bring RDO cloud online, ensure it works, then
move it again, and re-insure it works.

Again, the move can be made seemless by turning down some of the capacity in
nodepool.o.o and increase capacity in nodepool.rdoproject.org. And I am happy to
help work with RDO on making this happen.
