networking-ovn doesn't add IPv6 static route when external gateway is added to a router

[Numan Siddique]

Networking-ovn should add a row in Logical_Router_Static_Route with the default ip as "::/0" and next hop as the IPv6 gateway ip when an external network is added to the router and the external network has an IPv6 subnet.

Without this, the N/S routing will not work if the VM wants to send a N/S packet with the ipv6 destination ip other than the IPv6 public subnet

    Add IPv6 default route to OVN Logical Router

    Prior to this patch, only IPv4 subnets were accounted to install
    static routes on Logical Routers when setting a external gateway.
    This is a problem if the public network has an IPv6 subnet as
    instances won't get a default route.
