Ability to request TargetGroup only

[plaformsre]

Is your feature request related to a problem? Missing functionality to create an AWS TargetGroup without any type of an AWS Load Balancer. We have a use case where the Target Group has to be associated across AWS accounts and must not be associated to any other LB.

Describe the solution you'd like Create an AWS TargetGroup with one (1) or more Listeners without a Load Balancer solely with a K8S manifest that is being parsed by the AWS Load Balancer Controller.

The functionality is highly likely already there, what we need is a custom CRD being exposed called 'TargetGroup'.

Describe alternatives you've considered Creating the TargetGroup with Terraform or CloudFormation, but this is suboptimal as then we have to manage not only K8s manifests for deployment, but also other infrastructure code (e.g. Terraform, cloud-formation).
