Hi everyone.

Can I set X-Opaque-Id while using restHighLevelClient so that I can trace it in the slow log.

And if so, how to set?

Any advice is helpful.

best regards.

</div>

something like

```java
RequestOptions options = 
  RequestOptions.DEFAULT.toBuilder().addHeader("X-Opaque-Id", "my-id").build();

ClusterHealthResponse response = client.cluster().health(new ClusterHealthRequest(), options);

```
