melanie witt ef7e2a1988 Default to py3 for the pep8 tox env because it's stricter 
We recently fixed a couple of pep8 failures under py3 [0] which got
through because we're not gating pep8 on py3. This changes the python
version for the pep8 tox env to python3 because the py3 checks are
stricter. This updates the fast8 tox env as well.
