Don't add image entrypoint to the generate kube yaml

If no entrypoint or command is set in the podman create
command, and the image command or entrypoint is being
used as the default, then do not add the image command or
entrypoint to the generated kube yaml.
Kubernetes knows to default to the image command and/or
entrypoint settings when not defined in the kube yaml.
Add and modify tests for this case.
