Hello, I'm trying to create extension containing some custom health checks. One of the use cases is to provide health checks for all http dependencies. So I thought I could just map rest client configuration:

@ConfigMapping(prefix = "quarkus.rest-client")
public interface RestClients {
    @WithParentName
    Map<String, RestClient> clients();

    interface RestClient {
        String url();
        String scope();
    }
}

and for each url (after some clean up) I could create HealthCheck instance. I did some testing and obviously the following code won't work:

@Produces
    @Readiness
    List<HealthCheck> listOfHealthChecks() {
        return List.of(
                () -> HealthCheckResponse.named("Test 1").up().build(),
                () -> HealthCheckResponse.named("Test 2").up().build()
        );
    }

So how can I register them in the SmallRyeHealthReporter? There's no way I could do it manually (too many urls and repos). Additionally how should the HealthBuildItem creation look like?

Thank you
