NMDnsManager only uses one because it has to pass it to either
resolvconf or netconf, or for logging, or for IPv6 LL address
formatting.  We don't need it for anything else.  The problem with
resolvconf is that it uses the interface for priority rules which you
can modify via config files, so that say "eth0" is always preferred
above wlan0.  The problem with that is that the DNS information is
coming from a *network*, not an interface, and the network which an
interface is connected to can change.  So we don't want to talk about
*interfaces* here, we want to talk about networks instead.
