The Randomized Content Block XBlock only randomizes the selection of
the children blocks and has unpredictable randomization of
the order of the selected child blocks due to the usage of sets, which
are unordered, for storing the selected blocks. This becomes apparent
when all the available child blocks in a library are chosen for a
Randomized Content Block, to randomize just the order of the child
blocks and not just the selection of the blocks. The order of the
selected blocks ends up being similar for multiple learners.
This change modifies the XBlock to store the selected child blocks in
a list, instead of a set, after randomly shuffling them.

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
