      Description

      With https://issues.apache.org/jira/browse/KAFKA-9545, we exposed a possibility that a task could have been alive throughout the rebalance, while the input partitions actually change. For example, a regex subscribed source could have different topics when partitions are added/removed. We need to consider adding the support to expand/shrink the partitions across rebalance to keep task information consistent with subscription data.
