Added parameters to na_cdot_volume (#37202)

* Added parameters to na_cdot_volume

Before this commit there were no parameter for creating a volume
and exporting it as NFS volume. The added parameters are:
- *junction-path* for specifying where to mount the volume in the namespace
- *export-policy* for specifying which export policy to apply to the given namespace
- *snapshot-policy* if required, applying a snapshot policy for scheduling data protection tasks

* Sanity fixes

* Sanity fixes (2)
