docs(client-elastic-load-balancing-v2): Gateway Load Balancer adds a new feature (target_failover) for customers to rebalance existing flows to a healthy target after marked unhealthy or deregistered. This allows graceful patching/upgrades of target appliances during maintenance windows, and helps reduce unhealthy target failover time.
