Review Comment:
   Don't want to perform validations on any mount options as idea is to leave 
it to the admin if they are using the correct options are not. Cloudstack is 
only providing the functionality to add options.
   
   We can give an indication that this feature is tested with two mount options 
(`vers` and `nconnect`). But I am thinking that admin can give even more mount 
options if they desire to do so. That way we don't have to make any changes for 
supporting more options.
