* The original use of user.has_perm('can_take_proctored_exam') in the get_active_enrollments_for_course method had very poor performance when used for multiple learners. The permission is not designed for use in bulk operations. It was being called for each user in a loop by edx-proctoring, resulting in many queries to the database. This lead to timeouts on the client. This change exposes a new service endpoint that performs this permission checking in the database, resulting in one single query to the necessary LMS SQL tables and many fewer queries to the modulestore.
* bump version of edx-proctoring to 3.7.3

* Generate common/djangoapps import shims for Studio

We now either pass in the relevant courseoverview or when creating the
enrollement we use the factory which automatically creates the relevant
CourseOverview object for testing purposes.
