This involves moving from edx-private to github

Fix extracted from https://github.com/edx/edx-platform/pull/6035.

TNL-527

VIDEO_UPLOAD_PIPELINE setting be properly configured and that each
course be configured with a token issued by the media team for their
processing purposes (e.g. linking the video with a YouTube channel).

Fixed the edX middleware to lazily create request

Updates copy used in the checkbox label, constructs strings within the view instead of passing through a separate context variable, and alleviates unipain

Feature flagged. Puts a checkbox in the iframe. The iframe uses an organization_full_name parameter forwarded from Drupal by the courseware views and POSTs an email_opt_in parameter to the student views, preserving it on 403.
