> Currently /scans shows the monotonic time since a scan started as well as its "duration", which is the total amount of wall time for which a scanner was live.
> We should also publish other useful time metrics, like:
>  * cumulative CPU time
>  * cumulative I/O time
>  * a second wall time, including all time spent by the tserver servicing a scan (maybe that's just a sum of CPU and I/O time above?)
