If multiple CSI drivers exist, a default VolumeSnapshotClass can be specified
for each of them.
### VolumeSnapshotClass dependencies
When you create a VolumeSnapshot without specifying a VolumeSnapshotClass, Kubernetes
automatically selects a default VolumeSnapshotClass that has a CSI driver matching
the CSI driver of the PVC’s StorageClass.
This behavior allows multiple default VolumeSnapshotClass objects to coexist in a cluster, as long as
each one is associated with a unique CSI driver.
Always ensure that there is only one default VolumeSnapshotClass for each CSI driver. If
multiple default VolumeSnapshotClass objects are created using the same CSI driver,
a VolumeSnapshot creation will fail because Kubernetes cannot determine which one to use.
### Driver
Volume snapshot classes have a driver that determines what CSI volume plugin is
