Additional flake8 cleanup

The flake8 command was identifying several warnings and errors. This change
addresses the flake8 warnings and updates the setup.cfg with additional
exclusions. If accepted, jenkins will be updated to use the flake8 command,
rather than using the django_jenkins plugin. This will expedite jenkins
testing.
