Summary

Would be nice to document how to do volume imports using annotations. Like kthe following per Hendriks yaml samples:

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
name: blog-content-import-kubectl
namespace: ghost
annotations:
trident.netapp.io/importOriginalName: "to_import_kubectl"
trident.netapp.io/importBackendUUID: "11d28fb4-6cf5-4c59-931d-94b8d8a5e061"
trident.netapp.io/notManaged: "false"
spec:
accessModes:
- ReadWriteMany
resources:
requests:
storage: 5Gi
storageClassName: storage-class-nfs
