Description

This is follow-up of KAFKA-17011 that zk migration will encounter min=0 issue when the cluster consists of "new" broker and "old" controller.

The e2e `zookeeper_migration_test` [0] is a good test for online migration, but it does not test hybrid version. Hence, we can leverage it to increase test coverage.
