JIRA:EDUCATOR-5112

BREAKING CHANGES:
- `CORS_ORIGIN_WHITELIST` now requires URI schemes.
- Added new list `CORS_ORIGIN_WHITELIST_WITH_SCHEME` which contains all links of `CORS_ORIGIN_WHITELIST` with schemes and load the desired list after checking installed version.

This is intended for use in the Studio OAuth transition (ARCHBOM-1887) but
may be useful in the future as well.

Reverting because of errors seen in proctoring. The error from splunk:

 File "/edx/app/edxapp/venvs/edxapp/lib/python3.8/site-packages/edx_proctoring/views.py", line 590, in get
    data['onboarding_release_date'] = effective_start.isoformat()
AttributeError: 'NoneType' object has no attribute 'isoformat'

The effective date is coming from learning_sequences, which ultimately
comes from edx-when.

refactor: Use post_delete for date override

* feat!: Add data model for course app API
The current course apps API makes individual queries to determine if a course app is enabled, which can be inefficient. With this change we now have a Django model that contains this information, allowing us to make bulk queries about all the course apps for a course in the API.
It also adds a new signal handler that initialises the status of all course apps in a course on course publish.

* Use celery tasks and a management commands to make cache async

* Review feedback

* update log messages
use separate celery task for each course task

- moved send_activation_email to user_authn app

The new filter, called `permissions`, allows callers to filter courses

courses per roles, actions, etc.
