Title:
  MTU not applied on private ethernet interfaces

Status in netplan:
  New
Status in nplan package in Ubuntu:
  New

Bug description:
  Running nplan 0.30 on Ubuntu 17.10. From what I can tell, the
  ethernets/interface/mtu field isn't applied when testing against a
  private ethernet adapter.

  Using a netplan yaml file (/etc/netplan/10-ens7.yaml):

  ---

  network:
    version: 2
    renderer: networkd
    ethernets:
      ens7:
        mtu: 1450
        dhcp4: no
        addresses: [10.99.0.13/16]

  ---

  Then running "netplan apply" (or rebooting), yields the following:

  ---

  6: ens7: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
      link/ether 52:54:00:2a:19:bc brd ff:ff:ff:ff:ff:ff
      inet 10.99.0.13/16 brd 10.99.255.255 scope global ens7
         valid_lft forever preferred_lft forever
      inet6 fe80::5054:ff:fe2a:19bc/64 scope link
         valid_lft forever preferred_lft forever

  ---

  Is this a bug in netplan, or am I misunderstanding the YAML syntax?

  Best,
  Andrew
