qos_handler
This is an NSAPI AuthTrans function
It examines the QOS values in the request and compare them to the QOS limits.
It does several things :
1) It will log errors if the QOS limits are exceeded.
2) It will return REQ_ABORTED with a 503 error code if the QOS limits are
exceeded,
and the QOS limits are set to be enforced. Otherwise it will return REQ_PROCEED
