* [alpha] Improve Flex volume deployment

  * Flex volume driver deployment is simplified in the following ways:

    * New driver files can now be automatically discovered and initialized without requiring a kubelet or controller-manager restart.

Kubeadm: Automate certificate copy between control planes in HA setups

- Joining control plane nodes to a HA cluster can now be simplified by enabling the optional automatic copy of certificates from an existing control plane node.
- You can now use `kubeadm init --experimental-upload-certs` and `kubeadm join --experimental-control-plane --certificate-key`.

- Simplied validation error message for invalid fields by removing redundant field name. ([#132513](https://github.com/kubernetes/kubernetes/pull/132513), [@xiaoweim](https://github.com/xiaoweim)) [SIG API Machinery, Apps, Auth, Node and Scheduling]

- Kubeadm: graduated the kubeadm specific feature gate `UnversionedKubeletConfigMap` to GA and locked it to `true` by default. The kubelet related ConfigMap and RBAC rules are now locked to have a simplified naming `*kubelet-config` instead of the legacy naming `*kubelet-config-x.yy`, where `x.yy` was the version of the control plane. If you have previously used the old naming format with `UnversionedKubeletConfigMap=false`, you must manually copy the...

* controllers backoff better in face of quota denial ([#49142](https://github.com/kubernetes/kubernetes/pull/49142), [@joelsmith](https://github.com/joelsmith))
* The event table output under `kubectl describe` has been simplified to show only the most essential info. ([#51748](https://github.com/kubernetes/kubernetes/pull/51748), [@smarterclayton](https://github.com/smarterclayton))

* InfluxDB cluster monitoring has been deprecated as part of the deprecation of Heapster. Instead, you may use the [metrics server](https://github.com/kubernetes-incubator/metrics-server). It's a simplified heapster that is able to gather and serve current metrics values. It provides the Metrics API that is used by `kubectl top`, and horizontal pod autoscaler. Note that it doesn't include some features of Heapster, such as short term metrics for graphs...

- Kube-scheduler: a plugin enabled in a v1beta2 configuration file takes precedence over the default configuration for that plugin. This simplifies enabling default plugins with custom configuration without needing to explicitly disable those default plugins.
