The version of pbr we were using was having trouble parsing a new version
identifier for python-qpid, We have the pbr version hardcoded in many
places so update it to match whats currently in global-requirements.
Fixes bug #1470871

This is not an actual python project, so there is an amount of cruft
in the repo that is not needed. However, it does generate tarballs in
OpenStack Infra, so it needs the tox venv environment and the pbr
setup.py stuff. It also is totally possible to check python files in
the repo for flake8 violations, so set that up.
