If I understand your devstack plugin correctly, the build of the *.deb
is part of the installation process. I assume this takes some time. If
this is used in a gate test job, it will be done over and over again.
That's why the "apr" plugin [1] was build with the assumption that the
*.deb is pre-build and stored at a location reachable within a gate test
job. The PoC used the Ubuntu Cloud Archives to drill through things.

I have to finish other items before mid/end of August. After that I'd
like to have some kind of short coding-sprint/meeting with you (and
other interested people) to get things up and running. Combining forces
and stuff: https://www.youtube.com/watch?v=ZGegECwSiGY
