What does this PR do?

Adds the ability to skip the use of terraform helm and kubernetes providers via new variable create_kubernetes_resources

Adds a new output gitops_metadata this output will have the aws metadata from the aws resources created in terraform, this metadata is to be use with a gitops engine such as ArgoCD or FluxCD to pass this metadata over a gitops-bridge.

To see example how this output is used checkout the gitops-bridge terraform/examples/eks/
