Title: Add support to log trace messages to existing sink

Listkeys and 2I and other input stages to map-reduce jobs are implemented as a separate pipe that sends results into a downstream map_reduce pipe. This change allows the listkeys/2I/etc pipes to specific an existing sink (eg. the mr pipe) as the target for error trace messages. This is necessary in order to send listkey/2I errors back to the client.
