move target mapping to config.yaml - updated version (#682)

* move target mapping to config.yaml

* Update config.yaml

* Update common.go

* Add support for eks-1.0

Add also eks-1.0 to map

* chore: merge correction

* Move file only used for testing

* Tidier logs

* Add target mapping for GKE and EKS

* fingers cross this finishes target mapping
