add --raw for kubectl get

Adds a `--raw` option to `kubectl get` that allow you specify your URI, but use the transport built by `kubectl`.  This is especially useful when working with secured environments that require authentication and authorization to hit non-api endpoints.  For example, `kubect get --raw /metrics` or if you want to debug a watch with a view at the exact data `kubectl get --raw '/api/v1/namespaces/one/replicationcontrollers?watch=true'`.
