A new annotation, `service.beta.kubernetes.io/aws-load-balancer-target-group-attributes`, has been introduced for Kubernetes Service resources of type LoadBalancer to allow configuration of Network Load Balancer (NLB) target group attributes. This enables users to resolve hairpinning issues by setting `preserve_client_ip.enabled=false` and to track source IP addresses with `proxy_protocol_v2.enabled=true`, when the backend supports it. Using this feature requires the `DescribeTargetGroupAttributes` and `ModifyTargetGroupAttributes` IAM permissions.
