Public bug reported:

Steps to reproduce:

- Set up devstack with default settings from master
- Start an instance using e.g. the default cirros-0.3.4 image
- The instance will receive both an IPv4 and IPv6 address, but this isn't shown in the metadata, either on the configdrive or via http:

Expected result: The presence of an IPv6 network should be shown in the
metadata, in order to allow the instance to enable or disable IPv6
processing accordingly.
