> A single Kafka Streams instance can include multiple stream threads, and hence without
logging prefix it is difficult to determine which thread's producing which log entries.
> We should
> 1) add the log-prefix as thread id in StreamThread logger, as well as its contained StreamPartitionAssignor.
> 2) add the log-prefix as task id in StreamTask / StandbyTask, as well as its contained
RecordCollector and ProcessorStateManager.
