PVC Template Uses Deprecated Volume Annotation For storageClass

[pchang388]

I noticed that once we removed this, you may face an error for immutable/unable to change pvc resource if you were using the annotation method previously. This is because those annotations like storageClasses are considered immutable and you cannot change or remove those once created.

You could do two things:

1. Create a backup before using upgrading chart version ( do a helm rollback if it left you in an inconsistent state), remove the existing installation, and reinstall and import back up. This will ensure you are no longer using deprecated annotations that will go away and are using storageClasses moving froward.
2. Could optionally modify helm chart to have a variable like, legacyStorageAnnotations, and if it is true (default false), then use annotation headers for PVC storage class instead. This is just kicking the can down the road so it is preferred to do option 1
