Enhancement python3 support

Upgrade EOM to support Python3

- Primarily minor changes managed by the Python Six module
- Governor (L143-L148) has an issue with getting data out of redis; sometimes it gets None so it has to be reset.
- Also updated pep8 compliance based on what tox reported.
DRY: May be cleaner to set stdtmp once, since it does not depend on python version, and then only use the if statement to set sys.stderr. In fact, you could just do:

    sys.stderr = io.BytesIO() if six.PY2 else io.StringIO()
