CSI volume plugin is initial default for clusters running Kubernetes version 1.24 (or later)

With the announcement of support for Kubernetes version 1.24, the initial default storage class set for new clusters created by Container Engine for Kubernetes has changed from oci to oci-bv. As a result, the default volume plugin used to connect new clusters running Kubernetes version 1.24 (or later) to volumes from the Block Volume service is now the the CSI volume plugin rather than the FlexVolume volume plugin.

Existing clusters running Kubernetes version 1.23 (or earlier), and clusters upgraded to Kubernetes version 1.24, are unaffected.
