Bind dnsmasq in qrouter- namespace

Registered by Randy Tuttle on 2013-12-05

The intent of this blueprint is to allow binding of dnsmasq to the default gateway (i.e. qr-) interface in the qrouter- namespace for IPv6 tenant subnet in order to announce Router Advertisement with the default router pointing to the corresponding (i.e. qr-) interface. The behavior described in this blueprint is consistent with RFC 4861.

This blueprint serves as the foundation to leverage dnsmasq to support the following IPv6 Address Autoconfiguration methods for IPv6 tenant network, which are addressed separately by other blueprints.
1) SLAAC: https://blueprints.launchpad.net/neutron/+spec/dnsmasq-ipv6-slaac
2) DHCPv6 Stateful: https://blueprints.launchpad.net/neutron/+spec/dnsmasq-ipv6-dhcpv6-stateful
3) DHCPv6 Stateless: https://blueprints.launchpad.net/neutron/+spec/dnsmasq-ipv6-dhcpv6-stateless

The dnsmasq instance for IPv4-based tenant subnet will still stay in qdhcp- namespace.
