This PR attempts to improve the ability to collect analytics about learner's progress in their courses. Currently, the only place we regularly calculate course progress is when a learner visits the "Progress" tab in the courseware. Now, _optionally_, when a learner visits the home page of their course, we will enqueue a Celery task that will calculate their progress and emit a tracking event. This event is gated by use of the COURSE_HOME_SEND_COURSE_PROGRESS_ANALYTICS_FOR_STUDENT waffle flag.
