PoAn Yang updated KAFKA-18844:
------------------------------
Description:
In https://github.com/apache/kafka/pull/16848, we added kraft.version to
finalized features and got finalized features outside controller event handling
thread. This makes finalized features may be stale when processing
registerBroker event. Also, some cases like
QuorumControllerTest.testBalancePartitionLeaders become flaky cause of outdated
MV. This PR moves finalized features back to controller event handling thread
to avoid the error.
