- Looks at masquerading config for dates, outline, metadata, and
celebration APIs in course_home_api / courseware_api.
- Consolidates and cleans up places we check whether masquerading
gives us full access to a course.
This adds request caching to the following places:
* course expiration wrapper (displayed in Units)
* offer banner generation (displayed in Units)
* get_enrollment
* user_by_anonymous_id
* youtube_disabled_for_course
On a sample course with edx-val enabled, this reduced the queries
for a large sequence from 450 to 155.
* For all files, from __future__ import unicode_literals.
* Add @python_2_unicode_compatible to both models.
* Test six.string_type(obj) for both models.
Also, fix some new pylint warnings and improve model repr methods.

Develop the capability to allow instructors to designate teams to have private discussions. This way, so non-teammembers cannot view discussion. And the intend is for course teams to manage the team membership as well.
