In order to avoid having a MAC_Binding table explosion and helping
lowering the memory footprint when using ML2/OVN this patch is setting
two options to the OVN routers:
* always_learn_from_arp_request: By setting this to False we
avoid learning from ARP replies observed in the network. Only the
ARP requests sent by OVN will generate a MAC_Binding entry in the
OVSDB database. For larger broadcasts domains this avoids having a
MAC_Binding table explosion, reduce the DB size and memory footprint
of ML2/OVN.
* dynamic_neigh_routers: By setting this to True we avoid
pre-populating flows for router to router communication, reduding
the number of flows, DB size and memory footprint of ML2/OVN.
For more information on these option for core OVN please refer to:
https://www.ovn.org/support/dist-docs/ovn-nb.5.html
This patch also includes a new maintenance task to include these options
to existing routers in the system.
