What needs to be done to get patch_namespaced_deployment to work?
I want to update the image for one of my containers in a deployment and it seems I can't provide an UnversionedPatch. Using a valid JSON patch string, or the strategic-merge string I use in kubectl ends up with variations of 
```HTTP response body: {"kind":"Status","apiVersion":"v1","metadata":{},"status":"Failure","message":"json: cannot unmarshal string into Go value of type jsonpatch.Patch","code":500}```

Am I doing something wrong or is this not implemented yet? The link to UnversionedPatch returns a 404 https://github.com/kubernetes-incubator/client-python/blob/master/kubernetes/docs/UnversionedPatch.md If it's not implemented I'd be happy to work on it.
