This issue should be filed as a bug against either engine or vdsm (or
perhaps both).  An interface to set nfs options needs to be provided
through either the engine admin UI or through vdsm in some other way.
Manually editing and persisting files is ok as a workaround, but should
not be recommended or used long term.
