Michael Fraenkel 93c11422e4 CRI Portforward needs to forward websocket ports
- adjust ports to int32
- CRI flows the websocket ports as query params

- Do not validate ports since the protocol is unknown
  SPDY flows the ports as headers and websockets uses query params
- Only flow query params if there is at least one port query param
