Description of problem

The RDM (Raw Device Mapping) copy functionality for the NetApp ONTAP provider in the vsphere-xcopy-volume-populator does not work correctly. The RDMCopy implementation attempts to use ONTAP LUN clone APIs to copy RDM-backed disks, but this approach is not functional with ONTAP's storage architecture.

Root Cause

RDM disks require direct device mapping and cannot be handled through ONTAP's standard LUN cloning operations. The current RDMCopy implementation in NetappClonner is incompatible with how RDM devices work.

Proposed Fix

Remove the RDMCapable interface implementation and all RDM-related code from the ONTAP provider. The ONTAP provider should only support the VMDK/Xcopy method (VMDKCapable interface), which works correctly as the default fallback for all disk types.
