I am not sure that it's just about appending a new header in the "on_reply"
route with a some random value, because the "Expires" value of 200-OK
response must be between "Min-Expires" and "Expires" of the PUBLISH
request.  If we are talking about SUBSCRIBE, then Expires in the 200-OK may
be the same as in the request or should shorten.
