LEARNER-6313

Merge release back to master

Change access pattern for role/permissions retrieval to address Aurora query optimizer.

This is a fix for the performance issues in EDUCATOR-3374

AWS's Aurora backend for MySQL selects the wrong index on the
django_comment_client_role_users table, leading to performance issues.
This commit replaces that join with individual requests for permissions
for each role (of which there may be several for any given user).
It's dumber SQL, but Aurora will do the right thing.

Professional pathways are referred to as industry pathways in the code
to help differentiate them from professional certificate programs.
