[Users] Attach NFS storage to multiple datacenter

Well, as the downtime could be significantly decreased/the comfort for
an "migrate one vm, then the next" largely increased, if an nfs storage
could be mounted on multiple datacenters simultaneous i wonder if such a
feature is planed?

Main concern for me is that it might not really fit into the current way
of handling storage in ovirt.
