Setting ontap volume options such as atime-update

Sometimes you need to set a simple volume option such as :

• maxdirsize
• nosnap
• nvfail
• no_atime_update
• fs_size_fixed
• ...

and you might not immediately know where to do this. 
Chances are that you want to set these options the moment you create the volume.  Because there so many, wfa took a shortcut and bundled them all together in 1 variable called "options".
