Robert Li b092899b44 Support Router Advertisement Daemon (radvd) for IPv6
Launch radvd from inside l3 agent when any router port has an IPv6 address. If
slaac is used for IPv6 addresses, advertise the prefix associated with the port;
otherwise, advertise default route only.

Change-Id: Ib8b0b3e71f7af9afa769c41357c66f88f4326807
Implements: blueprint neutron-ipv6-radvd-ra
