Start the Controller, which in turn will bind to a TCP port as specified in the `akka.testconductor.port` config property, where 0 denotes automatic allocation. Since the latter is actually preferred, a `Future[Int]` is returned which will be completed with the port number actually chosen, so that this can then be communicated to the players for their proper start-up. This method also invokes Player.startClient, since it is expected that the conductor participates in barriers for overall coordination. The returned Future will only be completed once the client’s start-up finishes, which in fact waits for all other players to connect.
