Look for mongo client in the whole deployment

[glefloch]

As mentioned in #15589 this branch looks for mongo client in the whole deployment archive.

@mkouba I have a circular dependency :

io.quarkus.builder.ChainBuildException: Cycle detected:
		   io.quarkus.arc.deployment.BeanArchiveProcessor#build produced class io.quarkus.arc.deployment.BeanArchiveIndexBuildItem
		to io.quarkus.mongodb.deployment.MongoClientProcessor#mongoClientNames produced class io.quarkus.mongodb.deployment.MongoClientNameBuildItem
		to io.quarkus.mongodb.deployment.MongoClientProcessor#build produced class io.quarkus.arc.deployment.AdditionalBeanBuildItem
		to io.quarkus.arc.deployment.BeanArchiveProcessor#build

can I use ApplicationArchivesBuildItem#getAllApplicationArchives in this case?

can I use ApplicationArchivesBuildItem#getAllApplicationArchives in this case?

I think that it would be more correct to extract the BuildProducer<AdditionalBeanBuildItem> from the MongoClientProcessor#build() into a separate build step. Something like this should work:

@BuildStep
void additionalBeans(BuildProducer<AdditionalBeanBuildItem> additional) {
  additional.produce(new AdditionalBeanBuildItem(io.quarkus.mongodb.runtime.MongoClientName.class, MongoClientName.class));
  additional.produce(AdditionalBeanBuildItem.builder().addBeanClasses(MongoClients.class).setUnremovable().build());
}
