Start and stop scripts are outdated after Kubernetes update

Kubernetes no longer uses 'kubecfg', but rather 'kubectl'.
Therefore, the way that pods and services are being created
needs to be changed.

In order to create a pod, the parameter 'kind' needs to be set
to 'pod' in the yaml file and the api version specified.

The stop script now reads from k8s/{pod,service,replication}/ in order
to stop all the started pods, services, and replication controllers.
