Resources panel includes maximum resources actually used & warning when they are less than 50% of resources requested
We record high-water marks for RAM usage and print it out when crunch-run ends.
We also record total CPU usage (I think this is in CPU-seconds) but this isn't a very useful metric, we should record maximum maximum CPU seconds in a single interval.
In the "Resources" panel we should add an additional column which is for "Resources used" which has the maximum CPU % in an interval and the peak % RAM usage.
If either of those numbers are below 50%, the Resources panel should also include a note suggesting the user could reduce the requested cores or requested RAM.
