mixin: exclude iowait and steal from CPU Utilisation (#2194)
'iowait' and 'steal' indicate specific idle/wait states, which shouldn't
be counted into CPU Utilisation. Also see
https://github.com/prometheus-operator/kube-prometheus/pull/796 and
https://github.com/kubernetes-monitoring/kubernetes-mixin/pull/667.

Per the iostat man page:

%idle
    Show the percentage of time that the CPU or CPUs were idle and the
    system did not have an outstanding disk I/O request.

%iowait
     Show the percentage of time that the CPU or CPUs were idle during
     which the system had an outstanding disk I/O request.

%steal
     Show the percentage of time spent in involuntary wait by the
     virtual CPU or CPUs while the hypervisor was servicing another
     virtual processor.
