This is technically a revert of a revert that also includes some new
logic. The original PR was https://github.com/edx/edx-platform/pull/27770
and the revert PR was https://github.com/edx/edx-platform/pull/27973.

The new logic is to mock a request and create a module with user state
taken into account. We also put this into a celery task to help avoid
any potential concerns with recursing through children.
