This does a few things: * Update hacking to the version in global-requirements. Old hacking was installing a version of pbr that was breaking other packages. * Fix all the hacking/pep8 rules that updating hacking raised. * Do some general docstring cleanup, while already in there cleaning up a bunch of docstrings due to H405 violations.
