[Openstack] Metadata issue when using allowed address pairs

You won't be able to use the metadata service using an IP that isn't in the
fixed_ips list for a port. The way the metadata service associates a
request with an instance is only based on that field.
So if you want an IP to work with metadata, you'll have to add it to the
fixed_ips field for the port with a port-update.
