Reviewing https://console-openshift-console.apps.example.com/monitoring/dashboards/grafana-dashboard-api-performance?apiserver=kube-apiserver shows only OpenShift related resources in "etcd Object Count".

This is based on the fact that `etcd_object_counts` was deprecated in `kubernetes` version 1.21 and replaced with `apiserver_storage_objects` (see https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/CHANGELOG-1.21.md#other-cleanup-or-flake-3).

When running the query `topk(25, max(etcd_object_counts) by (resource))` from the above mentioned dashboard, only OpenShift resources are shown. But when running the query with `topk(25, max(apiserver_storage_objects) by (resource))` query it again shows all the expected resources. 

This means the dashboard on "/monitoring/dashboards/grafana-dashboard-api-performance?apiserver=kube-apiserver" showing "etcd Object Count" should be fixed and rather use `apiserver_storage_objects`.

OpenShift Container Platform 4.13.0-ec.1

- Always

1. Install OpenShift Container Platform 4.10
2. Access https://console-openshift-console.apps.example.com/monitoring/dashboards/grafana-dashboard-api-performance?apiserver=kube-apiserver and view "etcd Object Count" 

Only resources from `openshift-apiserver` are being reported. Core `kubernetes` resources and others are missing.

All resources within `etcd` to be reported and shown to understand how much object of each resource is available in `etcd`

This was raised a while ago in https://bugzilla.redhat.com/show_bug.cgi?id=2110365 and is still a problem in early OpenShift Container Platform 4.13 releases.
