* [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.

    * A sample DaemonSet to deploy Flexvolume drivers is now available.

* [prototype] Volume snapshots

  by default. The CSI drivers can make use of the `secretRef` values passed in `NodeExpansion`
  request optionally sent by the CSI Client from this release onwards. ([#121303](https://github.com/kubernetes/kubernetes/pull/121303), [@humblec](https://github.com/humblec))

- Fix: azure file mount timeout issue ([#88610](https://github.com/kubernetes/kubernetes/pull/88610), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider and Storage]
- Fix: corrupted mount point in csi driver ([#88569](https://github.com/kubernetes/kubernetes/pull/88569), [@andyzhangx](https://github.com/andyzhangx)) [SIG Storage]

### Action Required

* ACTION REQUIRED: Removes defaulting of CSI file system type to ext4. All the production drivers listed under https://kubernetes-csi.github.io/docs/drivers.html were inspected and should not be impacted after this change. If you are using a driver not in that list, please test the drivers on an updated test cluster first. ``` ([#65499](https://github.com/kubernetes/kubernetes/pull/65499), [@krunaljain](https://github.com/krunaljain))

- The in-tree cloud provider for vSphere has been deprecated and removed. Users are advised to utilize the external cloud provider and CSI driver available at https://github.com/kubernetes/cloud-provider-vsphere. ([#122937](https://...

* Fix a scalability issue where high rates of event writes degraded etcd performance. ([#64539](https://github.com/kubernetes/kubernetes/pull/64539), [@ccding](https://github.com/ccding))

  General Support for vSphere 6.7 will end on October 15, 2022. vSphere 6.7 Update 3 is deprecated in Kubernetes v1.24.  Customers are recommended to upgrade vSphere (both ESXi and vCenter) to 7.0u2 or above.  vSphere CSI Driver 2.2.3 and higher supports CSI Migration.
