Title:
  Network metadata fails to state correct mtu

Status in OpenStack Compute (nova):
  Fix Released
Status in OpenStack Compute (nova) mitaka series:
  In Progress

Bug description:
  Scenario:

  Instance is booted on Neutron tenant network with ML2 OVS driver and
  encapsulation. The MTU for that network is automatically calculated as
  1450. Instance has --config-drive=true set.

  Result:

  In <config_drive>/openstack/latest/network_data.json we get:

   "links": [{"ethernet_mac_address": "fa:16:3e:36:96:c8", "mtu": null,
  "type": "ovs", "id": "tapb989c3aa-5c", "vif_id": "b989c3aa-5c1f-
  4d2b-8711-b96c66604902"}]

  Expected:

  Have "mtu": "1450" instead.

  Environment:

  OpenStack Mitaka on Ubuntu 16.04
