Bug description:
  [Impact]
  Virtual devices such as VLANs, bridges and bonds may require the user to set a specific MAC address for proper operation on networks; where the same MAC may be used by default by the systems due to the methods used to create them.

  [Test case]
  /!\ This only works with the networkd renderer; NetworkManager does not currently support setting a MAC on bonds and bridges.

  1) Set a MAC address for a virtual device (bond, bridge or vlan),
  using the following syntax in netplan config:

  macaddress: ##:##:##:##:##:##

  2) Validate that the device gets the MAC address applied.

  [Regression potential]
  Failure to bring up a device configured in netplan or to set the MAC should be looked at as a possible regression. Other issues could include failure to write the configuration for networkd or NetworkManager.

  ----

  The expected hwaddresses are as follows:

  4: bond0: <BROADCAST,MULTICAST,MASTER,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default
      link/ether a0:36:9f:2d:93:80 brd ff:ff:ff:ff:ff:ff
      inet6 fe80::a236:9fff:fe2d:9380/64 scope link

  5: bond0.101@bond0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default

  Specifically
    bond0   | True | fe80::a236:9fff:fe2d:9381/64 |       .       |  link | a0:36:9f:2d:93:81

  Instead of expected a0:36:9f:2d:93:80

  The generated netplan.yaml does not set macaddress on the vlans at
  all.

  Where as the network_data.json does explicitely specifies the mac
  address to be in use for those vlans:

  "vlan_mac_address" : "a0:36:9f:2d:93:80"
