Add tracing in Java API Client

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):

OpenSearch client 3.x

Describe the issue:
Does anyone know if there’s any roadmap for implementing tracing on the Java API Client?


Would you be up for opening an issue in the github repo to solicit community input on the quesiton?

The meta issue is there [1], there are no work scheduled on the client yet since most of the work is happening on server side at the moment.
