MST-637: edx-proctoring 3.0.0 now requires a new key for use in ID
generation, starting from same value as SECRET_KEY (pre-rotation, but
rotation never happened for devstack.)

Remote config changes already made for relevant environments.

In commit 2723e0e2/PR #26162, we created a new version of the
`anonymous_id_for_user` method that would make it safe to rotate the
`SECRET_KEY` setting (without changing existing anonymous IDs). This
included a toggle to allow fast reversion to the old code if needed.

This commit removes the old code and the toggle as we are satisfied with
the correctness and performance of the new code.

[MST-636] Add additional check for proctoring requirements

Introduce and use a roles_api module, use the roles API in receivers that want to create or delete role assignments.
For new learners and admins, associate their user-role with the customer to which they are linked.
Does not yet specify the enterprise_customer for deletions. We want to maintain current behavior on deletes until we do a data backfill of that field. So for now, we'll continue to delete all assignments held by the deleted user.
Install django-cache-memoize, so that we can memoize roles (not assignments) in the Django cache.
