    KAFKA-6944; Add system tests testing the new throttling behavior using older clients/brokers
    
    Added two additional test cases to quota_test.py, which run between brokers and clients
with different throttling behaviors. More specifically,
    1. clients with new throttling behavior (i.e., post-KIP-219) and brokers with old throttling
behavior (i.e., pre-KIP-219)
    2. clients with old throttling behavior and brokers with new throttling behavior
