Alban Bedel 7ab936eafa Add an option to control if play kube should start the pod
Having play kube start the pod is not always appropriate, one might
for example like to have the pod running as a set of systemd services.
Add a `start` option to the command line and API to control if the pod
should be started or not; it defaults to true for backward
compatibility.
