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.
In a follow up match, we should replace marconi with a config option, so that it's more generic going forward.
