Reduce apiserver metrics cardinality of non-core APIs

Browse Source 
* Reduce `apiserver_request_duration_seconds_count` cardinality
by dropping series for non-core Kubernetes APIs. This is done
to match `apiserver_request_duration_seconds_count` relabeling
* These two relabels must be performed the same way to avoid
affecting new SLO calculations (upcoming)
* See https://github.com/kubernetes-monitoring/kubernetes-mixin/issues/498
