Subject: [PATCH] enable etcd latency metrics in kube-apiserver
kube-apiserver has a histogram etcd_request_duration_seconds that
measures latency between the kube-apiserver and etcd instance.
This metrics is currently dropped by cluster-prometheus. Enable
this metrics so we have visibility into etcd latency.
We ensured that this does not enable other unwanted metrcis
count by(name) ({name=~"etcd_request.+"})
etcd_request_duration_seconds_bucket
etcd_request_duration_seconds_count
etcd_request_duration_seconds_sum
