Title:
  Debian-format IPv6 information is not offered by the OpenStack HTTP
  metadata service.

Status in OpenStack Compute (nova):
  Expired

Bug description:
  Debian-format IPv6 information is not offered by the OpenStack HTTP
  metadata service.

  The debian-format IPv6 network information is not  offered by the HTTP
  Openstack metadata, whereas the metadata is present in the config
  drive.

  auto eth1
  iface eth1 inet static
      hwaddress ether fa:16:3e:8f:df:6f
      address 10.100.0.4
      netmask 255.255.255.240

  iface eth1 inet6 static
      hwaddress ether fa:16:3e:8f:df:6f

      gateway ::ffff:10.0.0.1
      dns-nameservers ::ffff:808:808 ::ffff:808:404

  Steps to reproduce:
  - create neutron network net1
  - create an IPv4 subnet for net1, with DHCP disabled
  - create an IPv6 subnet for net1, with DHCP disabled
  - create another network - net0, and add to it an ipv4 subnet with dhcp enabled, so that http metadata can be accessed
  - boot a vm with net0 as the first network and net1 as the second network

  Actual result:
  - Debian-format IPv6 information is not present in the HTTP metadata

  Expected result:
  - IPv6 information should be present in the HTTP metadata, as it is in the config drive

  Environment:
  - OpenStack Mitaka installed via Juju charms
  - Nova version: 13.1.2
  - Neutron version: 8.3.0
  - Hypervisor: KVM
  - VM: Windows Server 2012R2 or higher
