Documentation through maven build no longer matches the code base

The documentation is in here - https://developer.lightbend.com/guides/lagom-kubernetes-k8s-deploy-microservices/

It refers to kubernetes files located in deploy/kubernetes/xyz

This commit though removed those files b3f6ec9

Kindly document how to do the deployment now with a maven build
