--------------------------

    Attachment: kafka_604_v1.patch


1. Creating a KafkaTimer.time static function which takes a functor and (variable length) timers as input to support multiple timer.

2. add per-partition log flush timer.

3. make the log flush the time of flushing both the index and  data log

> It would be good if we add the following metrics:
> Producer: droppedMessageRate per topic
> ReplicaManager: partition count on the broker
> FileMessageSet: logFlushTimer per log (i.e., partition). Also, logFlushTime should probably be moved to LogSegment since the flush now includes index flush time.
