We need to backport a networkd fix:
https://github.com/systemd/systemd/commit/6fc2549711 . This will clean
up old addresses from interfaces when restarting networkd, so that
changed netplan configuration will actually reflect reality.

Bug description:
  For snappy (at first at least) we need to provide netplan in xenial,
  as for the first snappy GA release we must not use any PPAs any more.

  netplan's NetworkManager backend depends on two patches to read
  configuration and connections from /run/NetworkManager/. These will
  need to be backported for full netplan support; but they are not
  required for snappy as this will use a snapped NM. However, this will
  need a temporary hack
  (https://code.launchpad.net/%7Emorphis/netplan/+git/netplan/+merge/306607)
  until snaps can actually properly support OS components like
  NetworkManager.

  PATCHES:
  https://git.launchpad.net/~network-manager/network-manager/+git/ubuntu/commit/?h=xenial&id=6dcdb85
  https://anonscm.debian.org/cgit/pkg-systemd/systemd.git/commit/?h=ubuntu-xenial&id=4d4d305538

  REGRESSION POTENTIAL:
  netplan: The risk for existing installations is practically zero as nplan does not exist in xenial yet and thus will not be pulled in during upgrades.
  NetworkManager: Nothing in xenial expects/uses /run/NetworkManager/ and as it's an ephemeral tmpfs there is no risk of existing files there. If the patches are broken it could in theory happen that NetworkManager also does not properly read files from /etc/NetworkManager/ any more, so the -proposed package must verify that existing connections still work.

  TEST PLAN:
  1. Run "NetworkManager --print-config" and save the output.
  2. Install the proposed NetworkManager and confirm that existing connections (from /etc/NetworkManager/system-connections) still work.
  3. Run "NetworkManager --print-config" again and verify that the output is the same as in step 1.
  4. netplan has a very comprehensive integration test suite run as autopkgtest, which covers NetworkManager (including the /run patches) and network. Confirm that it succeeds.
