Are there some docs on how to do this somewhere? I added a task for us to
complete the work as part of the incubation request here:

Is the challenge here that celery has some weird license requirements? Or
that it is a new library?

When we started the Barbican project in February of this year,
oslo.messaging did not exist. If I remember correctly, at the time we were
doing architecture set up, the messaging piece was not available as a
standalone library, was not available on PyPi and had no documentation.

It looks like the project was moved to its own repo in April. However, I
can¹t seem to find the docs anywhere? The only thing I see is a design doc
here [1]. Are there plans for it to be packaged and put into Pypi?

We are probably overdue to look at oslo.messaging again, but I don¹t think
it should be a blocker for our incubation. I'm happy to take a look to see
what we can do during the Icehouse release cycle. Would that be
