If the NetFS Storage Pool Namespace XML data exists, format the
mount options on the MOUNT command line.

When the pool is started, the options will be generated on the
command line along with the exportfs options already defined.
To view the options of the running pool, use either 'nfsstat -m'
or 'grep $POOLNAME /proc/mounts' for the added Flags/options.
