Tracking waste due to preemption in the frontend monitoring
One thing that would be useful to monitor in the frontend is how much are we wasting due to preemption.
The schedd makes this easy to determine:
for any vanilla job that has not terminated, RemoteWallClockTime tells you how many seconds the job has wasted on the remote side.
The question is just how to record and display this info.
Similarly for NumJobStarts.
