Content Type Gating: Xblocks that have a graded component cannot be
accessed by audit track users.
- Caveats:
- In studio, instructors can set certain xblocks to be available to
all users, but graded components will default to not being
available for audit users
- If a course does not have a verified mode option, all users will
have access to graded content.
The Waffle Flag: The waffle flag is of for now.
It's name is: ```content_type_gating.debug```
This Commit Does NOT Include: Displaying for a user WHY they do not have
access to a specific piece of content. That change will be part of
another PR.
This commit "undoes"a previous hotfix, and allows a cms course_publish
signal to trigger a block_structure update_course_in_cache task, which
is run on an lms worker queue.
Changes:
-exposes ALTERNATE_QUEUE_ENVS
-adds routing layer in celery.py
-moves prior dev_with_worker settings file to devstack_with_worker
-moves course_block api functionality into openedx/core/djangoapps/content/block_structure
