For better user-facing performance, the SCORE_CHANGED signal is now handled by
enqueueing an async task to update the relevant stored grade, rather than
making the request wait until that operation finishes.

Some XModules are breaking their contracts and defining has_score but not
max_score.

Potential Grades revert PR

This reverts commit e3db08f1, reversing
changes made to 51c2444d.

The interface for custom management commands changed in Django 1.8 which
caused the `compute_grades` command to stop working. In order to fix it
I added an `add_arguments` method for specifying the accepted arguments
and updated the command to allow for passing a list of courses to run
the `offline_grade_calculation` against.

This management command has been broken since before the django 1.8
upgrade, so I'm deleting it and all its tests, and updating a few
other files that used these methods but are easily refactored away.

Basic architecture of Maintenance App - SUST-19, SUST-42. Implement Force Publish Course view. SUST-46

Adds ENABLE_SUBSECTION_GRADES_SAVED feature flag to both lms and cms. Also
installs the wiring that will allow robust grades to be used for courses
that enable it. This functionality is still gated by the feature flag
and should not be used until the remaining robust grades work is finished.
