    KAFKA-19352 Create offsets topic to fix flaky 
testCommitAsyncCompletedBeforeConsumerCloses (#19873)
    
    The flakiness occurs when the offsets topic does not yet exist. Hence,
    the issue is mitigated by creating the offsets topic in `setup()`. This
    serves as a workaround.  The root cause is tracked in
    [KAFKA-19357](https://issues.apache.org/jira/browse/KAFKA-19357).
    
    I ran the test 100 times on my Mac and all of them passed.
