This is original patch submitted to Github mirror, it was later resubmitted to
upstream Gerrit, where they are taking care of Python2.7. We can stick with
this version of patch for now because we don't care about py2.7 anymore.

Original-PR: https://github.com/openstack/pbr/pull/22
Upstream-PR: https://review.opendev.org/c/openstack/pbr/+/884789
