When using a private connection, we need to use dbus_g_proxy_new_for_peer() because the bus isn't involved. Since many parts of libnm-glib create a proxy for their corresponding remote object, consolidate the proxy creation logic. A later patch will add logic to use a private connection versus a bus-based one.
