Message: controller: Add load balancer hairpin OF flows.

Presently to handle the load balancer hairpin traffic (the traffic destined to the
load balancer VIP is dnatted to the backend which originated the traffic), ovn-northd
adds a lot of logical flows to check this scenario. This patch attempts to reduce the
these logical flows. Each ovn-controller will read the load balancers from
the newly added southbound Load_Balancer table and adds the load balancer hairpin OF
flows in the table 68, 69 and 70. If suppose a below load balancer is configured

10.0.0.10:80 = 10.0.0.4:8080, 10.0.0.5:8090, then the below flows are added

table=68, ip.src = 10.0.0.4,ip.dst=10.0.0.4,tcp.dst=8080 actions=load:1->NXM_NX_REG9[7]
table=68, ip.src = 10.0.0.5,ip.dst=10.0.0.5,tcp.dst=8090 actions=load:1->NXM_NX_REG9[7]
table=69, ip.src = 10.0.0.4,ip.dst=10.0.0.10,tcp.src=8080 actions=load:1->NXM_NX_REG9[7]
table=69, ip.src = 10.0.0.5,ip.dst=10.0.0.10,tcp.src=8090 actions=load:1->NXM_NX_REG9[7]
table=70, ct.trk && ct.dnat && ct.nw_dst == 10.0.0.10. actions=ct(commit, zone=reg12, nat(src=10.0.0.5))

Upcoming patch will add OVN actions which does the lookup in these tables to handle the
hairpin traffic.
