[~elek], I am sorry I missed your comment and committed the patch.
I missed adding the Tracing proxy in this patch. I have opened HDDS-1212 to
fix this.

> RPC Client should implement a retry and failover proxy provider to failover
> between OM Ratis clients. The failover should occur in two scenarios:
> # When the client is unable to connect to the OM (either because of network
> issues or because the OM is down). The client retry proxy provider should
> failover to next OM in the cluster.
> # When OM Ratis Client receives a response from the Ratis server for its
> request, it also gets the LeaderId of server which processed this request
> (the current Leader OM nodeId). This information should be propagated back to
> the client. The Client failover Proxy provider should failover to the leader
> OM node. This helps avoid an extra hop from Follower OM Ratis Client to
> Leader OM Ratis server for every request.
