This series allows to advertise routes for Load Balancer VIPs and
NAT external addresses to the network fabric.
The reason why this is posted as an RFC is because it depends on two
in-flight patch series in OVN:
* OVN Fabric integration: Northd (v4)[0]
* OVN Fabric integration: Ovn-controller (v5)[1]
v2:
* rebased on latest dependency patches [2]
* get_nat_addresses refactored to extract functionality for getting
LB addresses independently. The new function is called get_lb_addresses.
The original behavior of get_nat_addresses is unchanged.
* Added 'install_lflow' bool member to 'parsed_route' struct. This controls
whether northd installs logical flows for given route (cc @felix.huettner)
* Based on suggestion from dceara, "lr_stateful" input was added to en_routes
node. This allows for easier iteration over logical router's load
balancers.
* Based on suggestion from fnordahl, functionality was added to advertise
NAT/LB IPs of neighboring routers, if they have have "add_route" option
set to "true".
* A unit test was added to test this functionality.
* Based on the discussion about the option naming, the names were changed to
'dynamic-routing-nat' and 'dynamic-routing-lb-vips'. This will likely
change when dependency patch series gets updated to use
'dynamic-routing=<comma_separated_values>'
A more thorough tests (unit and system) are underway, but I wanted to get
this version out there, since it contains important changes.
(Manual testing looks good)
