/**
 * @assertion Future<Socket> detachSocket()
 * Detach the underlying socket from the HTTP client. When the socket is
 * detached the HTTP client will no longer perform any operations on it.
 *
 * This is normally used when a HTTP upgrade is negotiated and the communication
 * should continue with a different protocol.
 * @description Checks that this method detaches the underlying socket from the
 * HTTP client
