MINOR: config/proxy: Warn if a TCP proxy without backend is upgradable to HTTP 

If a 'switch-mode http' tcp action is configured on a listener with no
backend, a warning is displayed to remember HTTP connections cannot be
routed to TCP servers. Indeed, backend connection is still established using
the proxy mode.
