----------------------------------------

The patch sets a default threshold of 10 sec for request. If the value of {{warn.responseTime}} is configured as -1 then logging is ignored.

> Log the client and request details if the server discovers, when finally processing the request, that the current time minus arrival time of the request is beyond a configured threshold. 
> Look at the HBase {{responseTooSlow}} feature for inspiration.
