After initial switching setup, switch DHCP to external iface
After the external interface has been bound to Open vSwitch, we should not attempt to DHCP on it, as it won't receive the DHCP responses. Attempting to DHCP results in startup stalling on network-online.target, because systemd-networkd-wait-online.service looks at every network interface it should configure based on the [Match] sections, and waits for all of them to be configured by systemd-networkd, which will never finish if DHCP is broken.
