networkd should probably gain a way to define a default metric for all
routes defined on a specific .network, and maybe a second one as default
metric for all DHCP acquired routes on a specify network. That way you
could just set two different defaults for your two networks and the IP
stack will always use the right one.

Added to the TODO list.
