The read-only protection is more hassle than it's worth when testing locally and on stage. It's a solution to a problem we don't actually have, so I have reverted the changes.

common.test.acceptance.tests.video.test_video_module.YouTubeVideoTest.test_video_component_stores_speed_correctly_for_multiple_videos
is flaky, see for details.

By using the before_after library, we can force a race condition to reliably
occur in the CohortMembership.save() method. This unit test will do just that,
and ensure that our race-condition-handling code functions as it should.

Updating previously-existing unit tests to function with the new
CohortMembership model.

The code changes needed to get CohortMembership functioning properly.

The key of this change is twofold: first, CohortMemberships are unique
per-user, per-course. This is enforced at the database level. Secondly,
the updates are done using a select_for_update, which ensures atomicity.

These are the migrations needed for CohortMembership to function.
0005 establishes the table, 0006 will be used to move existing data
into the table as needed.

Per product guidance, we can just arbitrarily reassign problem users.
Implementing that decision, as well as the remainder of the data migration.

Also including a short script to re-run the 0006 migration after code changes
are live, to prevent a potential issue where the database become out-of-sync.
