Updates course caches in existing UpdateCourseStatsTimeslices class.
Open questions and concerns
Caches related to uploads raw data (update_upload_count, update_uploads_in_use_count, update_upload_usages_count) are not specific to the range of time defined by the timeslice. There is a TODO comment to improve this in the future. Not doing it right now as it's not related to revisions data.
Implement recent_revisions based on revision_count field from last timeslices. There is a TODO comment.
