Replace load average with PSI metric
The load average metric is misleading as a representation of CPU
saturation. Normal CPU utilization is a better real representation of
saturation.

On newer Linux, there is a new Pressure Stall Information[0] metric that
better represents CPU over saturation. This is also useful as it can
make single-core saturation more visible.
