[jira] [Created] (KAFKA-18634) Fix ELR metadata version issues

Colin McCabe created KAFKA-18634:
------------------------------------

             Summary: Fix ELR metadata version issues
                 Key: KAFKA-18634
                 URL: https://issues.apache.org/jira/browse/KAFKA-18634
             Project: Kafka
          Issue Type: Bug
            Reporter: Colin McCabe
            Assignee: Calvin Liu


Fix several ELR metadata version issues for 4.0

- Several places in the code just check MetadataVersion.isElrSupported rather than looking at whether the eligible.leader.replicas.version feature is enabled. We need to check the feature and not do ELR stuff when ELR is turned off.

- The documentation for MetadataVersion.IBP_4_0_IV1 should say which metadata records changed. Specifically, PartitionRecord, PartitionChangeRecord. It should also mention that ClearElrRecord was added in this MV.

- IBP_4_0_IV1 needs to be marked as stable.
