Adding collected structure to the course grade read

- Make it easier to rotate `SECRET_KEY` by documenting this usage
  for both sensitivity and rotation process. (ARCHBOM-1676).
- Just use a hash of the secret rather than HMAC + MD5. We're not
  authenticating a message, so HMAC isn't really needed -- it just needs
  to be unique, deterministic, and irreversible. SHAKE allows generation
  of an arbitrary length hash without needing to truncate.

Also, rename tracking session ID generator for clarity -- there's no
encryption happening here.

Add additional test for existing claim of uniqueness.

* import task decorator from celery APP instance instead of celery package in CMS

* replaced task decorator with shared_task in cms and common

* Fixed import of shared_task

* Fixed import

These changes were initially made to make it easier to do SECRET_KEY rotations.  Along the way, we found it made sense to refractor the code as well.

Changes made:
- changed get_to_create to create because now the code should only get to this block when a write is necessary
- added a lookup for anonymous_user_id. This is to return an existing anonymous_user_id rather than calculating. This will mitigate the results of SECRET_KEY rotation.
- Added monitoring to help us make better decisions: should we not sue SECRET_KEY, performance considerations...
- put old function behind toggle in case something goes wrong in production with new code
- refractoring function structure for better understanding

* changed instructor dashboard waffle type form course to legacy

[TSD] adds annotations for XBLOCK_RUNTIME_V2_EPHEMERAL_DATA_CACHE

This annotation was causing a linting failure, and a TypeError down the road in
the feature toggle report processing step by

Add an ADR about secret key usage.

Don't use secret keys for use cases which would result in breakage upon
rotation and which might slow down the act of rotation.
