------------------------------------
Summary: Create / Update changelog topics upon state store
initialization
Key: KAFKA-2804
URL: https://issues.apache.org/jira/browse/KAFKA-2804
Project: Kafka
Issue Type: Sub-task
Reporter: Guozhang Wang
When state store instances that are logging-backed are initialized, we need to
check if the corresponding change log topics have been created with the right
number of partitions:
1) If not exist, create topic
2) If expected #.partitions < actual #.partitions, delete and re-create topic.
3) If expected #.partitions > actual #.partitions, add partitions.
