Kubernetes instructions are out-of-date and no longer work

[vlal-zz]

Update the kubernetes instructions to create a working reproducible build.
Add a minikube deployment folder/instructions

[enxebre]

It'd be nice to build a helm chart for this

For clarity, the configuration in: https://github.com/microservices-demo/microservices-demo/tree/master/deploy/kubernetes is working. The documentation & instructions are the TODO here.

Same as #286

Fixed by @nustiueudinastea. See minikube PR https://github.com/microservices-demo/microservices-demo/pull/464/files

K8s on AWS was tested and works.
