Fix python3 compatibility

- Use six.moves for urllib2
- Use six.moves.xmlrpc_client
- Use six.moves.zip
- Adapt gettextutils
- Fix set() order dismatch for python 2/3
- Change dict key to list

Test:
- Build RPM with applied changes.
- Installed simplex controller checked to see if sm-api was running.
