metric-config: remove thresholds on userspace and kernel CPU

We do not need a default threshold on the userspace and kernel CPU
metrics because we already have a threshold on the overall CPU usage.
Sustained CPU usage is likely what someone wants to identify, no matter
which side of the accounting it is attributed to.  Delete the extra
thresholds.
