Prior to this patch the IGMP configuration for ML2/OVN was inconsistent
with the configuration option description and also the ML2/OVS driver
because it was flooding traffic to unregistered VMs [0].
The "igmp_snooping_enable" configuration option says:
"Setting this option to True will also enable Open vSwitch
mcast-snooping-disable-flood-unregistered flag. This option will disable
flooding of unregistered multicast packets to all ports."
But, in ML2/OVN that behavior was inconsistent prior to this patch
because it allowed traffic to flood to unregistered VMs. This patch
fixes it.
