Steps needed to remove Verified Track Cohort code:
- Review and merge 18974
- Ensure that there are CourseUserGroupPartitionGroup records for the cohorts to be migrated
- Generate a grade report for each course run before/after migration?
- Run separate data import script (creates MigrateVerifiedTrackCohortsSettings for the course runs to migrate)
- Notify course teams?
Run manage.py lms swap_from_auto_track_cohort
- Remove code (PR tbd)
