Log queue duration in production_json.log
`queue_duration` is a useful metric that is currently in api_json.log
but not in production_json.log. We should add it because it tells us how
long the request sat in Workhorse before Unicorn processed it. Having
this field enables the support team to better troubleshoot when delays
began to happen.
