Server to display total energy impact

[ArneTR]

Currently only the average energy impact is shown.

Would be nice to have the total per process

I believe some accumulating functionality is already implemented on energy impact, as the avg. energy impact goes down over time of the process is no longer available.

This is a bit counter intuitive, although identical to powermetrics. I believe it would be nicer to have the avg never change when the process ends, and then have the total energy impact as additional second dimension to use.
