Rework lb flow logic in order to visit first each load_balancer and then
related datapath during lb flow installation.
This patch allows to reduce memory footprint and cpu utilization in
ovn-northd.
Testing environment:
ovn-nbctl lr-list |wc -l
308
ovn-nbctl lb-list |wc -l
14524
Time needed for build_lrouter_lb_flows() to run for all datapaths/lbs
Total samples: 22
Maximum: 6937 msec
Minimum: 6869 msec
95th percentile: 6933.000000 msec
Short term average: 6916.599206 msec
Long term average: 6914.809656 msec

Lorenzo Bianconi (6):
northd: move snat_type out of vip loop
lib: link logical routers assigned for the same lb
northd: move build_empty_lb_event_flow in build_lrouter_flows_for_lb
northd: move lb_{skip,force}_snat code in
build_lrouter_snat_flows_for_lb
northd: get rid of add_router_lb_flow
northd: remove dead code in build_lrouter_nat_defrag_and_lb
