the `project/asdf1234/task_stats` endpoint currently requires you to list out the tasks for which you want stats. so if you just want all of the tasks, you have to query EVG for all of the tasks and then return them back in this query. so there's a workaround, but it just feels like we're pulling data out of evergreen only to give it right back to evergreen - would be nice if EVG could handle this for us.
no strong opinion on interface - maybe leaving the field blank returns all task stats?
