hackings current release is out of sync with global-requirements, *and* due to flake8 triggering pkg_resources checks, this results in a gate failure.

pbr 1.0.0 is installed because its available and compatible with global requirements, but this conflicts with the deps in many oslo projects and thus when flake8 triggers a consistency check, it fails. AIUI we had a similar issue with stevedore at one point.

Options to fix:
- get a new flake8 that does whatever stevedore did to avoid this (and update g-r to use it).
- monkey patch the same sort of thing in via hacking
- remove pbr 1.0 from g-r to give us breathing room.
- remove pbr 1.0 from pypi likewise.
