* Fixed issue when using OpenStack config drive for node metadata. Since we need to run commands such as blkid, we need to ensure that api server and kube controller are running in the privileged mode.

- kube-scheduler removed `AzureDiskLimits` ,`CinderLimits` `EBSLimits` and `GCEPDLimits` plugin. Given the corresponding CSI driver reports how many volumes a node can handle in NodeGetInfoResponse, the kubelet stores this limit in CSINode and the scheduler then knows the limit of the driver on the node. Removed plugins AzureDiskLimits, CinderLimits, EBSLimits and GCEPDLimits if you explicitly enabled them in the scheduler config. ([#124003](https://githu...

  as it requires installation of AzureFile CSI Driver. Users should enable CSIMigration and
  CSIMigrationAzureFile features and install the [AzureFile CSI Driver](https://github.com/kubernetes-sigs/azurefile-csi-driver)
  to avoid disruption to existing Pod and PVC objects at that time. Azure File CSI driver does not support using same persistent

feature gate is enabled, user should not upgrade to Kubernetes v1.22. vSphere CSI Driver does not support Kubernetes v1.22 yet because it uses v1beta1 CRD APIs. Support for v1.22 will be added at a later release. Check the following document for supported Kubernetes releases for a given [vSphere CSI Driver version](https://vsphere-csi-driver.sigs.k8s.io/compatiblity_matrix.html#compatibility-matrix-for-vsphere-csi-driver).

- Unlocked the `CSIMigrationvSphere` feature gate.
  The change allow users to continue using the in-tree vSphere driver,pending a vSphere
  CSI driver release that has with GA support for Windows, XFS, and raw block access. ([#116342](https://github.com/kubernetes/kubernetes/pull/116342), [@msau42](https://github.com/msau42)) [SIG Storage]

The in-tree AWS OpenStack Cinder driver "kubernetes.io/cinder" was deprecated in 1.16 and will be removed in 1.20. Users should enable CSIMigration + CSIMigrationOpenStack features and install the OpenStack Cinder CSI Driver (https://github.com/kubernetes/cloud-provider-openstack) to avoid disruption to existing Pod and PVC objects at that time.
