  **Updated** Prometheus telemetry behavior for inbound traffic to disable host header fallback by default. This will
  prevent traffic coming from out-of-mesh locations from potential polluting the `destination_service` dimension in
  metrics with junk data (and exploding metrics cardinality). With this change, it is possible that users relying on
  host headers for labeling the destination service for inbound traffic from out-of-mesh workloads will see that traffic

using vSphere. ([#59328](https://github.com/kubernetes/kubernetes/pull/59328), [@divyenpatel](https://github.com/divyenpatel))

* Emit number of bound and unbound persistent volumes as Metrics. This PR adds four kinds of Volume Metrics for kube-controller-manager: bound PVC numbers, unbound PVC numbers, bound PV numbers and unbound PV numbers. The PVC metrics use namespace as dimension and the PV metrics use StorageClassName as its dimension. With these metrics we can better monitor the...
