Extend #655 with a List Parser

[micw523]

Recently I proposed #655 that will work with Objects and Simple kinds. (See https://github.com/kubernetes/community/blob/master/contributors/devel/api-conventions.md) It is however, not capable of taking a list yet. I'll work on a kind: List parser that can create multiple objects at a time.
