Support subtree_edited_on and course_version fields in BlockStructures
TNL-5010

This change improves grading performance by combining what had previously been
multiple course tree traversals into a single traversal with combined
filtering logic.

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
