Bug description:
  The netplan configuration in ubuntu-raspi-settings (and more widely,
  the network-config in the gadget used on the server images) fails to
  rename the internal ethernet interface on Pi 3B and 3B+ models from
  "en<mac-address>" to "eth0". In the netplan case this is because the
  driver matching logic doesn't handle space-separate driver matches
  (although the underlying networkd system does); in the cloud-init case
  it simply refuses to rename interfaces that aren't matched by full MAC
  address.

  The intended fix is to stop attempting to do this via netplan or
  cloud-init, and simply handle this via a networkd .link file in
  ubuntu-raspi-settings. This will require an update to the relevant
  seeds as this package is currently only pulled into ubuntu-desktop-
  raspi, not ubuntu-server-raspi.
