**NetApp NVMe namespace support for in-use expansion**
Added support for in-use expansion of NetApp NVMe namespaces, allowing
volumes to be resized while attached to running instances without
requiring detachment. This feature enables seamless volume expansion
for NVMe-backed volumes in NetApp ONTAP environments.
Key capabilities:
* **In-use expansion**: Volumes can be expanded while attached to running instances
* **NVMe namespace compatibility**: Full support for NetApp NVMe namespace expansion
