These settings are used to toggle new authentication class in discussion and bookmarks app. The auth class is in openedx/core/lib/api/authentication.py and was added to replace deprecated OAuth2Authentication class in [rest_framework_oauth library](https://github.com/jpadilla/django-rest-framework-oauth)

* `count is deprecated. Use Collection.count_documents instead.` - I added a handful of simple workarounds for this pymongo deprecation that shouldn't increase the query counts

Also did some cleanup of unused code in pavelib after the recent split of the new `i18n_compilejs` command from `i18n_dummy`. (This had caused a diff-quality failure on the first commit.)

Remove ENABLE_SQL_TRACKING_LOGS and all associated code.
