Update hacking for Python3

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 vi check, it's now in
hacking as H106.

The tempest plugin is used on older branches as well.
We really only need hacking on this repo anyways,
where we no longer support python 2, so here we
make the requirement specific to python 3.
