[Bug 1579130] [NEW] need to support systemd.link renaming of devices in container

[Scott Moser]

Public bug reported:

We're interested in supporting network configuration of lxc containers
via maas/cloud-init yaml format.

The end goal is to do:
$ lxc init xenial x1
# enter into container and modify /var/lib/cloud/seed/nocloud-net/network-config
# to have something like:

% cat /var/lib/cloud/seed/nocloud-net/network-config
version: 1
config:
  - type: physical
    mac_address: "00:16:3e:3b:01:7a"
    name: foo2
    subnets:
      - type: dhcp
        control: auto

$ lxc start x1
$ lxc exec x1 /bin/bash

>From inside we expect to have a device named 'foo2' at this point that
has dhcp'd.

  From inside we expect to have a device named 'foo2' at this point that
  has dhcp'd.
