Thanks [~anu] for the review!
bq. Do you think we can maintain average time per op. So we can print out the

I like this idea, :). The new patch will addresses this.
bq. There is also an added detail that from the ozone-client perspective we
create one XcieverClient per pipeline( a set of datanodes). So when we close
the XcieverClient, we should probably collect this info.

Attach the updated patch.
