Description Luis Tomas Bolivar 2022-10-17 07:10:45 UTC 
Before adding support for lbs with VIPs on the provider networks, there was no need to react to gateway chassis creation events, and nothing was done for its deletion. However, after adding the support for that, there is a need of properly handling the creation event for that type of port.

The LogicalRouterPortEvent for gateway_chassis port are skip [1], however if ovn lb VIPs are on provider network, the create event needs to be handle so that the loadbalancer gets properly configured and added to the router

For the loadbalancer VIPs on the provider network, processing the event and triggering the lb_creat_lrp_assoc_handler means that the information about the logical router will be added, i.e., the router is added to the loadbalancer external_ids as a lr_ref, while the loadbalancer is also added into the logical_router object (loadbalancer entry). In addition, the lb is also added to the logical switches connected to the router.
