Description

KAFKA-6028 (KIP-219) changes the throttling behavior on quota violation as follows:

• the broker will send out a response with throttle time to the client immediately and mute the channel
• upon receiving a response with a non-zero throttle time, the client will also block sending further requests to the broker until the throttle time is over.

The current system tests assume that both clients and brokers are of the same version. We'll need an additional set of quota tests that test throttling behavior between older clients and newer brokers and between newer clients and older brokers.
