mgr/dashboard: Error cloning RBD image without 'layering' feature enabled
Only RBD images with 'layering' feature enabled can be cloned, but Ceph Dashboard is not validating this, so the user will see a generic error:
Ceph Dashboard should validate if the parent image has the 'layering' feature enabled, and display the corresponding validation message.

As discussed in the backlog grooming call today, the frontend should check if the layering feature is enabled and disable the "Clone RBD" button, if it's not (displaying a tooltip or giving some other visual hint on why cloning is not possible).
In general, the dashboard should prevent the user from running into errors before the action will be performed.
