Students can't create team in an instructor-managed topic

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.

MST-41

* no student change to instructor managed team

* Address comments & fix unit tests

* fix jenkins test failure

* Fix eslint errors

* Fix xss warnings

* Fix bokchoy test

 This is needed so Masters learners will not be in the same team as verfied and audit learners. If the team is designated as organization protected, it will not be visible or accessible by verified or audit track learners
MST-34

This is a follow up from MST-16, which was commited
in 3858036a.

Changes:
* Enrich course teams_configuration from a plain Dict
  to a custom XBlock field that uses the new TeamsConfig
  wrapper class.
* Remove teams_conf property from course, as the previous
  change made it redundant.
* Update teams_enabled implementation.
* Remove teams_max_size field from course, which is
  no longer semantically correct, as max team size
  is now defined on a teamset level.
* Remove teams_topics in order to discourage use of raw
  teams config dict.
* Add convenience properties teamsets and teamsets_by_id
  to course.
* Allow periods and spaces in teamset IDs to avoid breaking
  existing course teams.

Some parts of the code still use the old raw config data
(identifiable by searching "cleaned_data_old_format"),
which we expect to be slowly factored away as we build
new teams features. MST-40 has been created to remove any
remaining references if necessary.

MST-18

* fix: bokchoy test

* fix: remove pdb break

* 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.

MST-24

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.
MST-10

MST-6

Convert response bytes to str before JSON parsing.
