1. Proposed title of this feature request

Option to set multiple Storage Classes as `default`.

2. What is the nature and description of the request?

Doc[1] https://kubernetes.io/docs/tasks/administer-cluster/change-default-storage-class/#changing-the-default-storageclass

Since, now we can have multiple StorageClass marked as default. By default If more than one StorageClass is marked as default, a PersistentVolumeClaim without an explicitly defined storageClassName will be created using the most recently created default StorageClass. In case of cli & OCP console, using yaml we can surely make multiple StorageClass as default. We have an option to change the default StorageClass (Ellipsis in front of storage class and click set as default) but we do not ahve an option to make multiple StorageClass as default.

3. Why does the customer need this? (List the business requirements here)

None of the customers reported this RFE, I found this while testing during Red Hat internal OCP Hackathon 4.21 and I think this option might be helpful in future on our product.

4. List any affected packages or components.
