I wonder if there is some integration of sleuth in hazelcast. In my application I have hazelcast queue with event listeners configured for addEntity events and problem is that span seems to be broken once this listener triggeres. I know that there is integration of sleuth for ExecutorService, but is there something similar for com.hazelcast.core.ItemListener? Thanks in advance.

UPD: Giving more details.
I have some sample service that uses both spring-cloud-sleth and hazelcast queue

```
package com.myapp;

import com.hazelcast.core.Hazelcast;
import com.hazelcast.core.HazelcastInstance;
import com.hazelcast.core.IQueue;
import com.hazelcast.core.ItemEvent;
import com.hazelcast.core.ItemListener;
import java.util.concurrent.Executors;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.cloud.sleuth.DefaultSpanNamer;
import org.springframework.cloud.sleuth.TraceRunnable;
import org.springframework.cloud.sleuth.Tracer;
import org.springframework.scheduling.annotation.Async;
import org.springframework.stereotype.Service;

@Service
@Slf4j
public class SomeService {

private HazelcastInstance hazelcastInstance =
    Hazelcast.newHazelcastInstance();
private IQueue<String> queue = hazelcastInstance.getQueue("someQueue");

private Tracer tracing;

@Autowired(required = false)
public void setTracer(Tracer tracer) {
    this.tracing = tracer;
}

{
    queue.addItemListener(new ItemListener<String>() {
    @Override
    public void itemAdded(ItemEvent<String> item) {
        log.info("This is span");
        log.info("This is item " + item);
    }

    @Override
    public void itemRemoved(ItemEvent<String> item) {
    }
    }, true);
}

@Async
public void processRequestAsync() {
    log.info("Processing async");
    log.info("This is span");
    Executors.newSingleThreadExecutor().execute(
        new TraceRunnable(tracing, new DefaultSpanNamer(), () -> log.info("Some Weird stuff")));
    queue.add("some stuff");
}

}

```

and once I call processRequestAsync I receive following output in console:

```
INFO [-,792a6c3ad3e91280,792a6c3ad3e91280,false] 9996 --- [nio-8080-exec-2] com.myapp.SomeController            : Incoming request!

```

So looks like span was broked once we go to eventListener code and I wonder how can I propagate or create new span inside hazelcast queue
