mod_rest: Use logger of HTTP request in trunk
In Prosody trunk rev c975dafa4303 each HTTP request gained its own log
sink, to make it easy to log things related to each request and group
those messages. Especially where async is used, spreading the request
and response apart as mod_rest does with iq stanzas, this grouped
logging should help find related messages.
