The goal of this change is to remove the registration of signal handling from pkg/kubelet. We now pass in a stop channel. If you register a signal handler in `main()` to aid in a controlled and deliberate exit then the handler registered in `pkg/kubelet` often wins and the process exits immediately. This means all other signal handler registrations are currently racy if `DockerServer.Start()` is directly or indirectly invoked. This change also removes another signal handler registration from `NewAPIServerCommand()`; a stop channel is now passed to this function.
