Merlin Mao d10801e983 Allow Replayer to report the results of TraceRecords. (#8657) 
Summary:
`Replayer::Execute()` can directly returns the result (e.g, request latency, DB::Get() return code, returned value, etc.)
`Replayer::Replay()` reports the results via a callback function.

`DBTest2.TraceAndReplay` and `DBTest2.TraceAndManualReplay` are updated accordingly.
