Admin can see a list of dates and how many running assignments are on each date. #1015
Description
For scheduling purposes (for upgrades/maintenance), it would be useful to see if there are any dates that don't have much or any assignment activity. This is partially implemented in that you can check to see if there are assignments running on a particular date. The downside is that you have to guess and check multiple dates to find one that is relatively clear. An improvement on this would be just to list the dates and a count of how many assignments are running on each date.
Listing all future dates might be a bit unnecessarily complex in terms of database queries, so this listing could be limited to just one month at a time.
