Kubernetes SIG Storage Introduction and Update

summary
SIG Storage describes concrete changes: CSI migration translates legacy in-tree volume types (aws-ebs, azure-disk, azure-file, gcepd, cinder, vSphere) to CSI and targets GA by 1.24; self-managed clusters must install replacement CSI drivers and flip feature gates in order. Windows support uses csi-proxy (GA v1.22) to perform privileged ops via gRPC. New access mode readWriteOncePod appears (alpha in 1.22). Skip volume ownership cuts mount time from >30 minutes to seconds for large volumes.
