All these TODOs means that: now `BatchInfo#streamIdtoNumRecords` will track
both the input stream's received data (for receiver-based stream) and
to-be-processed data number (for receiver-less stream). So the semantics in
`StreamingJobProgressListener` is slightly different.
Take `totalReceivedRecords` as an example: should we add the receiver-less
input stream's number of to-be-processed record into here, since it is not
actually received yet. So we have to figure out this semantics difference.
