Django 2.0 will make this field required for `ForeignKey` and `OneToOneFields`.
In previous versions the option defaulted to `models.CASCADE` when not
specified. This change should make the deprecation warnings in the current
Django version go away.
The migrations where also modified, but the changes should not cause a change in
the database schema since `models.CASCADE` was already the old default.
Add a new waffle switch that allows us to assume zero grades for
learners who have no entry previously recorded, and another to
disable persisting grades for unengaged learners.

Remove deprecated SingleSectionGrader. TNL-5987
Remove display_name and module_id from Scores objects
Update CourseGradeFactory.__init__ to not be user-specific
Update some callers to use CourseGrade class instead of "summary" dict
Remove no longer needed course_grades.py module.
Renamed django signal from GRADES_UPDATED to COURSE_GRADE_CHANGED
Makes use of the new SUBSECTION_SCORE_CHANGED signal to trigger a task that
updates persisted course grade values. We've also renamed SCORE_CHANGED to
PROBLEM_SCORE_CHANGED to head off any issues with unclear signal names.

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.

The "oauth_body_hash" appeared twice in the auth header in the request
when posting grade back to tool consumer. However, the signature sent
from edX is calculated based on only one oauth_body_hash.
On the tool consumer side, the signature is calculated based on the auth
header and will use the duplicated fields. So the signatures will not match.
And request will fail the signature validation.
The bug was introduced in this commit:
03cee389e0
on July 12th by updating the oauthlib.
Because 0.7.2(original version) doesn't have oauth_body_hash support, so a custom
OAuth1 client was implemented to add oauth_body_hash to the headers:
f5d0f3ff55/lms/djangoapps/lti_provider/outcomes.py (L24).
However, the new oauthlib 1.0.3 has support for oauth_body_hash
(51675237c4 (diff-c2a1e5f1ddfe8e48ff62b59eb952644eR180)).
So after updating library, oauth_body_hash is added twice.
This fixes the bug by removing the custom client and use the oauthlib
default client to generate the auth header.
* First take at forcing a subsection's grade to update when a signal is
sent that a problem's score has changed
* Refactor signal handler connection.
* Expand bokchoy tests to cover progress page
* Add some grading unit tests
