Braden MacDonald 96e5ff8dce feat: store split modulestore's course indexes in Django/MySQL

Split modulestore persists data in three MongoDB "collections": course_index (list of courses and the current version of each), structure (outline of the courses, and some XBlock fields), and definition (other XBlock fields). While "structure" and "definition" data can get very large, which is one of the reasons MongoDB was chosen for modulestore, the course index data is very small.

By moving course index data to MySQL / a django model, we get these advantages:
* Full history of changes to the course index data is now preserved
* Includes a django admin view to inspect the list of courses and libraries
* It's much easier to "reset" a corrupted course to a known working state, by using the simple-history revert tools from the django admin.
* The remaining MongoDB collections (structure and definition) are essentially just used as key-value stores of large JSON data structures. This paves the way for future changes that allow migrating courses one at a time from MongoDB to S3, and thus eliminating any use of MongoDB by split modulestore, simplifying the stack.

Status: Maintenance

Responsibilities
================
The Discussion app powers the Open edX forums experience.

Direction: Move and Extract
===========================
Discussions related functionality is scattered across a number of places and should be better consolidated. Today we have:

* ``lms/djangoapps/discussion``
* ``openedx/core/djangoapps/django_comment_common``
* ``openedx/core/lib/xblock_builtin/xblock_discussion``

Ideally, what we want in the long term is for all of this extracted into a new repository that holds the code for both the inline discussion XBlock as well as all the Django apps.

That being said, it's not clear what the path forward for this app is. Forum functionality is something that has not been actively worked on for a while, and it's been suggested that we should remove this app altogether in favor of having better integration with other more established forum software. This decision is usually complicated by the desire to have tight integration with courseware and access to data for analytics.

Regardless, check with Product before undertaking any major refactoring work here.
