Logs WQ status disconnects differently from normal

Currently, a Work Queue status check behaves like a client. By this I mean that there is no ready message that sets the hostname. Also there is no instance, that I am aware of, of a worker requesting work queue status. Therefore, I am renaming the hostname from "unknown" to "QUEUE_STATUS". Handle_worker then checks if the host name is "QUEUE_STATUS", if it is the log records that the status worker disconnected. @btovar please review. #219
