Subject: [PATCH] Implement copy constructor for class Monitor

To support the instance copy of Monitor like the following:
    AMQP::Monitor monitor(consumer);
    consumer->bindExchange(exchange, AMQP::direct).onSuccess([&, monitor](){
        // do something when the consumer is ready!
        if(monitor.valid())
            consumer->doSomething();
    });
