trace - Quarkus with Microprofile OpenTracing distributed tracing doesn't work

Question

I'm migrating Thorntail (2.4.0.Final) to Quarkus (1.11.1.Final). During test phase we have noticed that distributed tracing is not working. Tracing works (single component traces) but uber-trace-id is not passed with rest request header, so next microservice (recipient of rest request) is generating Trace from zero without span info.

In Thorntail it was done just by configuration on ClientBuilder

import org.eclipse.microprofile.opentracing.ClientTracingRegistrar;
import javax.ws.rs.client.ClientBuilder;
...
ClientBuilder clientBuilder = ClientBuilder.newBuilder();
...
ClientTracingRegistrar.configure(clientBuilder);

Comparing both I have noticed that with Thorntail there was ClientTracingRegistrarProvider available

public class ResteasyClientTracingRegistrarProvider implements ClientTracingRegistrarProvider {
    public ResteasyClientTracingRegistrarProvider() {
    }

    public ClientBuilder configure(ClientBuilder clientBuilder) {
        return this.configure(clientBuilder, Executors.newFixedThreadPool(10));
    }

    public ClientBuilder configure(ClientBuilder clientBuilder, ExecutorService executorService) {
        ResteasyClientBuilder resteasyClientBuilder = (ResteasyClientBuilder)clientBuilder;
        Tracer tracer = (Tracer)CDI.current().select(Tracer.class, new Annotation[0]).get();
        return (ClientBuilder)resteasyClientBuilder.executorService(new TracedExecutorService(executorService, tracer)).register((new Builder(tracer)).withTraceSerialization(false).build());
    }
}

with all wildfly related configuration like file META-INF/services/org.eclipse.microprofile.opentracing.ClientTracingRegistrarProvider with provider path org.wildfly.swarm.mpopentracing.deployment.ResteasyClientTracingRegistrarProvider

In Quarkus we are building rest client in the same way and there is no such provider. Is anybody aware what we need to change to have this distributed tracing feature?

Additional info: we are building rest client with jaxrs API (javax.ws.rs) and building app with dependencies:

        <dependency>
            <groupId>io.quarkus</groupId>
            <artifactId>quarkus-resteasy</artifactId>
        </dependency>
        <dependency>
            <groupId>io.quarkus</groupId>
            <artifactId>quarkus-smallrye-opentracing</artifactId>
        </dependency>

Thanks in advance for all suggestions and help.
