[API] date endpoint for the gradebook_history_api.feed
https://community.canvaslms.com/ideas/8437-graderid-endpoint-for-the-gradebookhistoryapifeed
The gradebook_history_api.feed (https://canvas.instructure.com/doc/api/gradebook_history.html#method.gradebook_history_api.feed) contains just about all the details we need, but it would be very helpful if an optional date endpoint (like the optional assignment_id and optional user_id), were available. If the date endpoint would be available, only one call would be needed to retrieve all the information for that date, (student, grader, assignment, score, etc.).
The GET /api/v1/courses/:course_id/gradebook_history/:date call retrieves the assignments and graders for that date, but does not give the amount of detail as the GET /api/v1/courses/:course_id/gradebook_history/feed call, so would require more calls to retrieve the rest of the information.
