Merge two kubernetes contexts into one config file

This was created with the help of where it is explained how you can use two contexts from two different files at once. However sadly it was not explained how to save this state to a kubernetes config file in order to get rid of the need to export every time.

So here it is:

export KUBECONFIG=emptyfile:conf1.yml:conf2.yml

kubectl config get-contexts
kubectl config view --raw=true > config
