NodePort information returned in context should be a dictionary

In Kubernetes context, NodePort information returned in context should be
a dictionary. In [1], the node information is dumped in a yaml file. The
NodePort object doesn't have a serialize implementation; instead of
returning the object, an equivalent dictionary should be returned.
