sometimes run past their task duration, for example, in cases of supervisor
failover. Setting earlyMessageRejectionPeriod too low may cause messages to be
dropped unexpectedly whenever a task runs past its originally configured task
duration.|no (default == none)|

disable druid to consume Kafka in a transactional way. And druid could consume
lower version of Kafka now, such as 0.10.2.1 |no (default == true)|
