* 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)
