    KAFKA-8995: delete all topics before recreating (#8208)
    
    I think the root cause of KAFKA-8893, KAFKA-8894, KAFKA-8895 and 
KSTREAMS-3779 are the same: some intermediate topics are not deleted in the 
setup logic before recreating the user topics, which could cause the 
waitForDeletion (that check exact match of all existing topics) to fail, and 
also could cause more records to be returned because of the intermediate topics 
that are not deleted from the previous test case.
    
    Also inspired by https://github.com/apache/kafka/pull/5418/files I used a 
longer timeout (120 secs) for deleting all topics.
