 Description   
When the build agent node is very busy, the graph shows < 4%.
The build configuration is hitting the vm hard and cpu usage on the vm shows > 90%
From the code for v10, it shows QB is reporting sys cpu usage.
com.pmease.quickbuild.plugin.measurement.core.supplier.CpuMetricsSupplier
return sysInfo.getCpuUsage().getSys();
OSHI Docs: SYSTEM = CPU utilization that occurred while executing at the system level (kernel).
We would like it should show combined (overall/total CPU usage)
return sysInfo.getCpuUsage().getCombined()
