Kayobe consumes the bifrost stable branches. We often get bitten by
changes to bifrost (and its deps) in master, and the stable branches
shield us from this while allowing for bug fixes.

Secondly, while the version of bifrost & its dependencies isn't tied
to those of the cloud infrastructure, it does simplify things somewhat
to be able to say everything is running code from series X.

We don't use the bugfix branches.

I'm honestly unsure if the regular stable branches are used (outside of the Kolla CI), let alone bugfix branches. (I also doubt that Bifrost releases are very popular or even meaningful, but that's another topic.)
