For example, if you used pod.GenerateName, pod.Name might be the empty
string while p.Name contains the actual name of your pod. Thus passing
pod.Name can result in a `resource name may not be empty` error.
Since PodInterface.Create returns the server's representation of the
pod, which may differ from the api.Pod object passed to Create, we do
the same from the framework's pod creation functions. This is useful if
e.g. you create pods using Pod.GenerateName rather than
Pod.Name, and you still want to refer to pods by name later on
(e.g. for deletion).
