The TripleO team is working on ppc64le right now and should be uploading
ppc64le containers to docker.io in a few weeks.  I'm pretty sure the ppc
team is using kolla to build the containers, but I'm not 100% sure as the
ppc64le container build jobs are in a 3rd party ci system.

I'm checking with some folks to get the details that would be helpful here.
