MINOR: http: Log warning if (add|set)-header fails
This patch adds a warning if an http-(request|reponse) (add|set)-header
rewrite fails to change the respective header in a request or response.
This usually happens when tune.maxrewrite is not sufficient to hold all
the headers that should be added.
