New TargetGroupBinding Custom Resource

When employing load balancers in AWS, the AWS Load Balancer Controller introduces a new capability through a custom resource (CR) called TargetGroupBinding. This CR enables you to expose your pods by associating them with an existing target group. With this approach, you can manage the load balancer independently of Kubernetes while utilizing the configuration specified in Kubernetes objects. If your operational workflows involve creating load balancers external to Kubernetes, TargetGroupBinding permits you to use the Target Group ARN instead of relying on Kubernetes annotations.
