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.
* Added ability to do official vs dev builds (need to add to the
RPM builds now)
* Reverted changes to awx/wsgi.py after talking with Chris C.
regarding the pathing issues and created config/wsgi.py instead
that is installed to /var/lib/awx
* Cleaned up package scripts so there's less junk being written to
the screen during the install/uninstall
