Slawek Kaplonski 5a9258d3d2 Fix multicast traffic with IGMP snooping enabled 
In the ML2/OVS when igmp_snooping is enabled but there is no
external querier multicast traffic will stop working after few minutes
as packets will not be flooded to tunnel/external bridges.

So this patch sets "mcast-snooping-disable-flood-unregistered" option
of the br-int to False (default value) even when igmp_snooping is
enabled in the neutron-ovs-agent's config file.

Additionally it configures "mcast-snooping-flood-reports" and
"mcast-snooping-flood" on patch ports in br-int to True.

That way we can provide best effort snooping: multicast isolation where
IGMP queriers are available and flood everywhere else?
