Gian Merlino 08c784fbf6 KafkaIndexTask: Use a separate sequence per Kafka partition in order to make (#2844) 
segment creation deterministic.

This means that each segment will contain data from just one Kafka
partition. So, users will probably not want to have a super high number
of Kafka partitions...

Fixes #2703.
