Ephemeral Storage capacity change - Forbidden

[brickpattern]

Environment:
AWS EKS : latest
Scylla Operator : v1.11
Setup: 5 node cluster ( 1:1 scylla node to EKS node) with XFS storage on the NVME disk on the instance.
Storage type : ephemeral
Issue: underlying EKS node instance has enough storage . Attempt to increase the storage capacity in scylla.yaml resulted in below error.

spec.datacenter.racks[0].storage: Forbidden: changes in storage are currently not supported

Is this a bug report or feature request?

• Feature Request

What should the feature do:
Increase the storage of the scylla node as permitted by the underlying ephemeral storage. When a cluster is operational with data, setting a capacity attribute be honored if the underlying ephemeral storage has enough volume to accomodate.

What is use case behind this feature:
If this is not supported, how else do we increase or replace the scylla nodes maximizing the storage capacity?

This issue is inherited from Kubernetes StatefulSets (see kubernetes/kubernetes#68737) the workaround is suggested in #825

Closing as dupe of #1103
