Title: left-over code tweaks from cross-merge

* `parent` and `parents` were changed to `parent_id` and `ancestor_ids`, but a new piece of code was not changed before merge. Change it here.
* requests module is annoying with logging. Turn it off.
* KA exposes exercises that are not "live". Don't include them in our topic tree (10 total)

This is tested and ready to go.
