 In order to enable this feature, we should set feature gate `ExpandPersistentVolumes` true and turn on the `PersistentVolumeClaimResize` admission plugin. Once `PersistentVolumeClaimResize` has been enabled, resizing will be allowed by a Storage Class whose `allowVolumeExpansion` field is set to true.
