Jeff Cohen f03b141f05 fix: do not clear request cache when running eager Celery tasks (#31261) 
Clearing the RequestCache was intended to address memory leaks in the
celery workers. Celery worker processes will process many tasks before
they are terminated. RequestCache cleanup typically happens in the
RequestCacheMiddleware class, and middleware never executes for celery.
To get around that issue, the CLEAR_REQUEST_CACHE_ON_TASK_COMPLETION
setting was created to clear the RequestCache after every task was
successfully completed.

This works fine when celery is running as a separate process, as it's
set up to do in production. But during development, the
CELERY_ALWAYS_EAGER setting variable is set to True, meaning that
celery tasks are run in the same thread as the Django Request. This is
meant to make debugging easier, as task failures run as part of the
request cycle and will raise exceptions that are visible to the
browser.

However, celery tasks are triggered from many different actions. That
means that the RequestCache was being cleared many times during the
course of processing a request. This led to behavior that was
potentially slower, but also incorrect–the RequestCache was getting
flushed in a way that wouldn't happen in any deployed environment
because celery would be running in separate processes there. This came
up when trying to fix an issue around extra history records being
created during problem submissions:

  https://discuss.openedx.org/t/extra-history-record-stored-on-each-problem-submission/8081

Furthermore, it's not necessary to prevent RequestCache memory leaks
when running in CELERY_AWLAYS_EAGER mode in development because the
middleware cleanup happens automatically–as everything is running as
part of the request/response cycle.

There are times in which we may want to run celery eagerly and still
clear the cache, such as testing. I have set
CLEAR_REQUEST_CACHE_ON_TASK_COMPLETION = False in all dev and test
environments that already have CELERY_ALWAYS_EAGER = True. The unit
test that specifically tests whether the request cache is getting
cleared upon completion of a celery task then overrides
CLEAR_REQUEST_CACHE_ON_TASK_COMPLETION = True even though
CELERY_ALWAYS_EAGER = True for the sake of that specific testing
purpose.
