Allow setting NFS shares config in NetApp/NFS mode

This is currently necessary as the NetApp driver does not
handle this on its own in all cases (although it does in some).

I've reported a bugreport about this upstream, but meanwhile

that we find.

We use the internalURL endpoint for non-admin usage, but that's still
the admin network.
