Title:
  (Network) Config Version 2 is not working on CentOS 7.4

Status in cloud-init:
  Expired

Bug description:
  We're using CentOS 7.4.1708.
  My config (using NoCloud ISO):

  #### meta-data
  #cloud-config
  instance-id: iid-<hostname>
  local-hostname: <fqdn>

  #### user-data
  #cloud-config
  write_files:
    - content: |
        # This file is automatically generated by cloud-init!
        172.29.6.61 <fqdn> <hostname>
        127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
        ::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
      path: /etc/hosts

  #### network-config:
  version: 1
  config:
    - type: physical
      name: eth0
      subnets:
        - type: static
          address: <ip>/16
          dns_nameservers:
            - <DNS1>
            - <DNS2>
          dns_search:
            - <DNS_DOMAIN>
    - type: route
      destination: 0.0.0.0/0
      gateway: <GATEWAY>

  I've disabled NetworkManager, and enabled the 'old' network daemon
  with chkconfig.

  Things that do not work:
  gateway is not set (either in the network-scripts/ifcfg-eth0 file or in the routes table). I've also tried to set the default gateway inside the subnet block, doesn't work either.

  resolv.conf is empty, except for a comment that cloud-init visited the
  file.... :(

  I've tried using Config Version 2, but that fails horribly (not even
  the IP is set). Even when enabling NetworkManager things go hay-wire
  real soon (things like dhclient interfering, having a DHCP address as
  well as a static address...)

  I only want 3 things:
  - simple network configuration with IP, GW, DNS and DNS Lookup Domain
  - hostname
  - hosts file

  I don't care if i have to use the Legacy ENI, Config Version 1 or
  Config Version 2, i just want it to work...

  Can anyone provide a working example?
