Adds "Manage" sub-tab to course "Teams" tab
with UI for downloading and uploading team
membership CSVs. The upload and download function-
ality are currently not implemented.
The new tab only appears when the user is course staff
and the course has at least one instructor-managed
team-set, which is not the case for any existing
courses, so not current course staff will see this
change.
This ticket will be followed-up upon in MST-44 and
MST-49.

* Add @python_2_unicode_compatible to 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.
