- for self paced courses, if a sequential's due date has passed
  and it is incomplete, allow the user to reset the start_date
  for the related schedule to now, thus shifting all due dates
  for all sequentials within the course by the pre determined
  due date offset.
- add historical table to the Schedule model.

We should use encodeURIComponent instead of encodeURI when encoding part of uri like querystring. encodeURI does not encode `+` sign. For example a query string parameter like `scope=user_id+profile+email` is not encoded by `encodeURI` which results in invalid url on select multiple enterprise page.

ENT-1961 | Making the manual enrollment reason field optional via configuration flag `ENABLE_MANUAL_ENROLLMENT_REASON_FIELD`.

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.

Currently, Resubmit photo-verification button is not been displayed
inside the approval box on dashboard.In order to allow a learner to

consistent with implementation. Using
characters limit instead of word limit.
