Provide -o vers= support for mount_nfs.
Our mount_nfs does use -o nfsv<2|3|4> or -2 or -3 to specify the version. OSX (these days), Solaris, and Linux use -o vers=<2,3,4>. With the upcoming autofs support we can make a lot of (entrerprisy) setups getting mount options from LDAP just work by providing -o vers= compatibility.
