Adding support of k8s / OpenShift

[ibuziuk]

@jakewright do you think if it will be useful from tutorial perspective to contribute k8s / openshift orchestration support to this compose microservice example (maybe to the root of the tutorials project e.g. new 'k8s' / 'openshift' folder) ?

@jakewright if you are interested in orchestration would be happy to contribute ;-)
