The only way to use update3/monitor_cond_since with OVS currently is to use ovs 2.17+ and enable RAFT for the ovsdb-servers. Even though ovsdb-server should be able to use monitor-cond-since without RAFT, it currently does not.
There isn't really anything to do in neutron or ovsdbapp for this. It will be used automatically if the ovs version / setup support it.
