Revert "[PROD-1287] - initial work to optimise problem_grade_report code."

Background: I use private.py a lot in my devstack for my private configurations. But issues are raised when I need to change/override a setting that is defined in devstack_docker.py file. Since that file's contents are loaded after private.py, my private.py is useless against the settings in devstack_docker.py.

Description: Now that the devstack is dockerized, I think it makes more sense to import the private.py in the devstack_docker.py files i.e. at the end of configuration files hierarchy.
