Public bug reported:

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.

Steps to reproduce:
- create neutron network
- create an IPv4 subnet for that network, with DHCP disabled
- create an IPv6 subnet for that network, with DHCP disabled

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
