Review Comment:
this makes the code better orgainized. However, if we return the final
report via the `controller.liveReports method`, it changes the semantics of the
/liveReports endpoint when a query finishes. previously this endpoints return
404 when a query finishes, by above suggestion, a 200 with final report will be
returned. And even if this behaviour change is OK, returning a final report via
the /liveReport endpoint looks weired.
So I will keep `liveReports` method but add a new `finalReport` method
independently
