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.
This commit starts writing course indexes (active_versions) to both MySQL and Mongo, but continues to read from MongoDB only.
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.
Includes:
- general documentation
- links to individual events definitions and location
- adding examples to events docs
- adding annotations at the trigger location

* Add COURSE_ENROLLMENT_CHANGED: sent after the enrollment update
* Add COURSE_UNENROLLMENT_COMPLETED: sent after the user's unenrollment
* Add CERTIFICATE_CREATED after the user's certificate generation has
been completed
* Add CERTIFICATE_CHANGED: after the certification update has been
completed
* Add CERTIFICATE_REVOKED: after the certificate revocation has been
completed
* Add COHORT_MEMBERSHIP_CHANGED: when a cohort membership update ends
This helper is used by the LMS, CMS, _and_ `openedx.core`,
so let's move it to `openedx.core` to reduce import complexity.
The following files no longer import from LMS:
- cms/djangoapps/contentstore/management/commands/edit_course_tabs.py
- lms/djangoapps/ccx/migrations/0006_set_display_name_as_override.py
- openedx/core/djangoapps/ccxcon/api.py
- openedx/core/djangoapps/verified_track_content/models.py
- openedx/features/course_experience/plugins.py
Note: The LTI XBlock has a dependency on this import path (!?);
a fix can be found here [1].

* Renamed OAuth2Authentication to BearerAuthentication
* Added back OAuth2Authentication name
-there are libraries such as edx-enterprise that still import OAuth2Authentication. The OAuth2Authentication class should be fully removed when everything is importing BearerAuthentication correctly
- Removing deprecated auth classes
- Replacing OAuth2AuthenticationAllowInactiveUserDeprecated with OAuth2AuthenticationAllowInactiveUser
- the old class was a child class of a deprecated class that we are removing and replacing.
* Added new auth class
- Created new class called OAuth2AuthenticationAllowInactiveUser, which replaces old class with same name
- Renames previous OAuth2AuthenticationAllowInactiveUser to OAuth2AuthenticationAllowInactiveUserDeprecated
- Replaced all imports of OAuth2AuthenticationAllowInactiveUser to call deprecated class instead
- testing new class in discussion(added flag based on django setting)
