MINOR: proxy: report a warning for max_ka_queue in proxy_cfg_ensure_no_http()

Display a warning when max_ka_queue is set (it is the case when
"max-keep-alive-queue" directive is used within a proxy section) to inform
the user that this directives depends on the "http" mode to work and thus
will safely be ignored.
