add a switch to disable @Incoming just like @Scheduled myMethod.cron.expr=disabled

Description

This is to seek a specific solution for https://github.com/quarkusio/quarkus/issues/19278.

I have a simple Quarkus app that includes both HTTP API and Kafka consumer, I would like to run a HTTP API only version and a fully version in my K8S cluster. Because the code base is very small, I don’t want to separate code into three jars: common service jar + http resource jar + kafka consumer jar. Because I don’t hope the Kafka consuming issue affects HTTP API service performance and stability, I want that HTTP API only version.

So I want a switch to disable @Incoming:

@ApplicationScoped
public class MyConsumer {
    @Incoming("topicA")
    public void consume(Xxx x) {
    }
}

application.properties:

mp.messaging.incoming.topicA.disabled=true     # currently Quarkus doesn't support this config property

Implementation ideas

Add a new runtime config property like mp.messaging.incoming.[TOPIC].disabled with default value false.

@Dieken can you give it a try and tell us if it works you’d expect?

Funny enough there already is an option to disable a channel with mp.messaging.incoming|outgoing.<channel>.enabled=false. It prevents the channel from being registered.
