Make External Load Balancer templates work with IPv6

This change modifies the network isolation templates that allow for
fixed IP addresses on the controllers' IPs and VIPs, and makes them
compatible with IPv6 addresses.

The latest version of the patchset creates an from_service_v6.yaml
in order to properly handle service VIPs on IPv6 networks.

Note that since OVS is not currently compatible with IPv6 tunnel
endpoints, this patch does not yet enable IPv6 for the Tenant
network by default.
