This patch enables the "mcast_flood_reports" and "mcast_flood" (on provnet
ports only) options in the Logical Switch Ports in the OVN driver. Without
these options, the ovn-controller will consume the IGMP queries and won't
send it to the LSP ports, meaning that external IGMP queries will never
arrive to the VMs.
In talks to the core OVN team, it was suggested [0] to enable the
"mcast_flood_reports" option by default in the OVN driver (at least until
fixed in core OVN) as a workaround to this problem. And, to avoid having
to update all ports (which can be many) based on the igmp_snooping_enable
configuration option, we are always setting "mcast_flood_reports" to
"true" in the LSPs. This won't cause any harm (also confirmed by core
OVN developers [0]) since it will be ignored if multicast snoop is
disabled.
