Add traffic distribution configuration to optimize Inter-AZ data transfer costs by enabling zone-aware traffic routing. This change introduces a new trafficDistribution field that allows configuring traffic locality preferences, zone affinity rules, and cross-AZ traffic minimization strategies. The implementation reduces cloud egress charges by prioritizing same-zone service-to-service communication while maintaining high availability through intelligent failover to other availability zones when local resources are unavailable.
