en_northd engine nodes provides the created or updated logical routers in its tracked data and en_lr_stateful node handles those changes.
This is built on Mark Michelson's patch series located here https://patchwork.ozlabs.org/project/ovn/list/?series=465828 this is required because the datapath refactor was required in order to accomplish incremental processing of the logical routers also built with the first two patches of this series by Lorenzo Bianconi located https://patchwork.ozlabs.org/project/ovn/list/?series=466579. He brought in some changes required to dynamically allocate the sizes of the datapaths array.
