Bug description:
  [Impact]
  Users of netplan may wish to specify a custom MTU value for a device.

  [Test case]
  - Run nplan integration tests on the release
  - Validate that netplan generate && netplan apply alone, without config, behave as expected (no result)
  - Validate that netplan generate && netplan apply with minimal config writes /run/NetworkManager/conf.d/10-globally-managed-devices.conf
  - Validate that netplan generate && netplan apply works with any existing configuation.
  - Use the config below; ensure behavior is as expected (STP value is set on the interface; adjust device names as appropriate). There should be no errors at applying the requested configuration.
  - Use the config below with the 'stp' key; the device should be brought up and include the default value set for the kernel.

  [Regression potential]
  STP default value should continue to be used for the bridge configured using netplan if STP is unset in configuration.

  ---

  networkd supports setting STP value in Bridge type netdevs, but
  netplan does not accept the key.
