I don't think this class is needed at all, instead just keeping the
OperatingSystemLoad class is fine. Then in DrillMetrics we have to `register`
that instead of calling registerAll on this class.
Reason being we only have a single metric here not actually a set so we
should use `register` instead of `registerAll`.
