Currently, neutron tunnel endpoints must be IPv4 addresses, i.e. $HOST_IP, although IPv6 endpoints are supported by most drivers. Create a TUNNEL_IP_VERSION variable to choose which host IP to use, either HOST_IP or HOST_IPV6, and configure it in the OVS and Linuxbridge agent driver files. The default is still IPv4, but it can be over-ridden by specifying TUNNEL_ENDPOINT_IP accordingly. This behaves similar to the SERVICE_IP_VERSION option, which can either be set to 4 or 6, but not 4+6 - the tunnel overhead should be consistent on all systems in order not to have MTU issues. Must set the ML2 overlay_ip_version config option to match else agent tunnel sync RPC will not work. Must set the OVN external_ids:ovn-encap-ip config option to the correct address. Updated 'devstack-ipv6-only' job definition and verification role that will set all services and tunnels to use IPv6 addresses. Closes-bug: #1619476 Change-Id: I6034278dfc17b55d7863bc4db541bbdaa983a686
