Bug 2278389

Description of problem (please be detailed as possible and provide log
snippests):
Once the Fusion Data Foundation operator was upgraded to 4.14 we encountered an issue with the backingstore going into a rejected state with a reason of "no capacity", which is a generic error for noobaa not being able to talk to the storage for the backingstore.

During troubleshooting in today's session  with the customer we encountered an error reporting ENOTSUP (Error Not Supported) and it was due to the backing storage for the storage class (Netapp Trident) not supported xattrs that Noobaa now has a requirement in ODF 4.14 which was not present in ODF 4.12, this issue is documented here: https://github.com/noobaa/noobaa-core/issues/7843. This was preventing the backingstore from coming ready and communicating with the Netapp Trident Storage.

Version of all relevant components (if applicable):
OCP 4.14/ODF 4.14

Does this issue impact your ability to continue to work with the product
(please explain in detail what is the user impact)?
Yes, Backing store is down

Is there any workaround available to the best of your knowledge?
No

Rate from 1 - 5 the complexity of the scenario you performed that caused this
bug (1 - very simple, 5 - very complex)?
