ovn-northd: Minimize number of ARP/NS responder flows for DNAT.
Most ARP/NS responder flows can be configured per datapath instead of per
The only exception is with distributed gateway router ports which need
special treatment. This patch changes the ARP/NS responder behavior and adds:
- Priority 92 flows to reply to ARP requests on distributed gateway router
ports, on the chassis where the DNAT entry is bound.
- Priority 91 flows to drop ARP requests on distributed gateway router ports,
on chassis where the DNAT entry is not bound.
- Priority 90 flows to reply to ARP requests on all other router ports. This
last type of flows is programmed exactly once per logical router limiting
the total number of required logical flows.
