etcd_object_counts is deprecated and replaced with apiserver_storage_objects, causing "etcd Object Count" dashboard to only show OpenShift resources

Issue

• Reviewing https://console-openshift-console.apps.foo.bar/monitoring/dashboards/grafana-dashboard-api-performance?apiserver=kube-apiserver shows only OpenShift related resources in "etcd Object Count".
• etcd_object_counts only reports OpenShift resources and is missing kubernetes core resurces.
• Starting with OCP 4.10, etcd_object_counts does no longer correctly report number of objects per resources.
