A common usage pattern is to make an exam that is restricted to a
particular enrollment track. Since there is no UI in Studio to do this
at the sequence/subsection level, course authors instead restrict every
unit in the sequence to that track (e.g. "verified"). The legacy
courseware experience could handle this, but the Course Blocks API does
not. It is likely that we'll want to permit toggling this at the
sequence level, but regardless of whether we do that going forward, we
still have to deal with this kind of content data in existing courses.
An entirely empty sequence is useless, and currently breaks the
Courseware MFE browsing experience. This commit introduces the first
part of that fix, invoking the new Learning Sequences API to remove
sequences that the user shouldn't be allowed to know about. The plan is
to switch over the entire course outline from the Course Blocks API to
the Learning Sequences API, and this is the first small step in that
direction.
This also creates CourseWaffleFlag learning_sequences.use_for_outlines
to control the gradual rollout of this feature. This will start as a
very limited rollout to address courses that show this specific bug
(TNL-8377).
