The repo is Python 3 now, so update hacking to version 3.0 which supports Python 3. Fix problems found. Update local hacking checks for new flake8. Remove hacking and friends from lower-constraints, they are not needed to be installed at run-time. Change-Id: I602e3f3dd3f158799f910d73ac9c759efe15fcc0
