Change all `system.cpu.*.pct` metrics to be scaled by the number of CPU cores such that the values range on `[0, 100% * number_of_cores]`. This will make the CPU usage percentages from the system cpu metricset consistent with the system process metricset. The documentation for these metrics already stated that on multi-core systems the percentages could be greater than 100%. This makes the code match the docs, but does cause a change in behavior to the user. (cherry picked from commit 67e2064)
