Produce EventLoopGroup build item

[scrocquesel]

Allow other extensions to reuse the EventLoopGroup that is effectively used without making assumptions on the presence of Vert.x extension.

As a non-CDI expert, I'm not sure if there's a better way to expose those suppliers. Consumers would implement a build step as follows:

@BuildStep(onlyIf = AmazonHttpClients.IsAmazonNettyHttpServicePresent.class)
@Record(ExecutionTime.RUNTIME_INIT)
void setupClient(EventLoopGroupBuildItem eventLoopGroupSupplier, ...) {
    produceSyntheticBean(..., recoder.createClientWithEventLoopGroup(eventLoopGroupSupplier.getMainEventLoopGroup());
}

The drawback is that supplier must return a singleton since it can be called multiple times.

@cescoffier could you take a look at this one?

There is already a io.quarkus.netty.deployment.EventLoopSupplierBuildItem which does the same. Do I miss something?

@cescoffier If no io.quarkus.netty.deployment.EventLoopSupplierBuildItem is present, the netty extension actually create default ThreadPools which are not exposed. I think the buildStep cannot consume and produce io.quarkus.netty.deployment.EventLoopSupplierBuildItem at the same time.

Ah, I see. This must be added in the javadoc, as it's a bit confusing to have two very similar build items.

Already put some explanations on both build items. Would you mind help me rephrase to make it clearer ?

@cescoffier friendly ping :)

@cescoffier friendly ping :) It would be great if it could be merged for 3.1. I'd like to refactor AWS extension to use the same event loop. I have made some commits to the AWS sdk and it is now possible to configure most of the used ThreadPool and EventLoop. I just need this PR to complete the work in AWS extension.

Sorry for the delay, the last few weeks got chaotic.

Can you rebase to have another ci run?
