#### Metrics
* [stable] Add support for cloudprovider metrics for storage API calls. See [Controller manager metrics](https://kubernetes.io/docs/concepts/cluster-administration/controller-metrics/) for more information.

   * <p>We manage calls to this method carefully, to signal only when necessary, but never losing a

### Client
* Use Prometheus instrumentation conventions ([#36704](https://github.com/kubernetes/kubernetes/pull/36704), [@fabxc](https://github.com/fabxc))
* Clients now use the `?watch=true` parameter to make watch API calls, instead of the `/watch/` path prefix ([#41722](https://github.com/kubernetes/kubernetes/pull/41722), [@liggitt](https://github.com/liggitt))
