Upgrade Django to 1.4.22

Updating documentation for team_membership endpoint

ECOM-2114

Add sorting by team_count, as well as secondary sort (by name).

Recent changes to the team_membership API endpoint added the
course_id optional parameter, but the in-code documentation
was never updated to reflect this. The wiki documentation at
https://openedx.atlassian.net/wiki/display/TNL/Team+API is OK.

This reverts commit cea274dc, reversing
changes made to 02cf9cac.

Only let global staff (is_staff=True) see the Proctoring tab in the Instructor Dashboard if the feature flag is enabled.

By doing this, we can prevent the bug where multiple users can join
a team simutaneously and push its enrollment over the defined
maximum value. Tests have also been added to confirm this behavior.

TNL-3061

Specify course key when retrieving credit requirements.

The 1.4.22 security fix makes it so that empty sessions are not written.
To keep the tests working, we now log in the user, so that some data is
saved to the session.

SOL-1125: fix for organization id drop down not populating

Expand instructor definition

By moving the team_page.first_member_username access to occur before
click_first_profile_image() is called, we avoid a potential issue
where the wrapper() method defined in page_object.py, which
decorates the property, calls into _verify_page() and raises a
WrongPageError.

ECOM-2117

The stale flag needs to take into account its previous state.
