Readme file refers to describe a different service name

[vcarmen]

According to the Kubernetes template "kube-hello-change.yaml", the hello-flask-change-service is created, but the Readme file points to describe "hello-python-service".

Please, update the Readme file: kubectl describe services hello-flask-change-service instead of the kubectl describe services hello-python-service command, also update its output.

Thanks!
