> We can validate error codes from JoinGroupResponses and HeartbeatResponses. Currently this includes:
> - JoinGroupRequest to the wrong coordinator returns NOT_COORDINATOR_FOR_CONSUMER
> - JoinGroupRequest with an unknown partition assignment strategy returns UNKNOWN_PARTITION_ASSIGNMENT_STRATEGY
> - JoinGroupRequest with an out-of-range session timeout returns INVALID_SESSION_TIMEOUT
> - JoinGroupRequest on a brand new group with an unrecognized consumer id produces UNKNOWN_CONSUMER_ID
> - JoinGroupRequest with mismatched partition assignment strategy compared to the rest of the group returns INCONSISTENT_PARTITION_ASSIGNMENT_STRATEGY
> - JoinGroupRequest on an existing group with an unrecognized consumer id produces UNKNOWN_CONSUMER_ID
> - A correct JoinGroupRequest returns NONE
> - HeartbeatRequest to the wrong coordinator returns NOT_COORDINATOR_FOR_CONSUMER
> - HeartbeatRequest with an unknown group returns UNKNOWN_CONSUMER_ID
> - HeartbeatRequest with an unrecognized consumer id returns UNKNOWN_CONSUMER_ID
> - HeartbeatRequest with generation id mismatch returns ILLEGAL_GENERATION
> - A correct HeartbeatRequest returns NONE
> We can validate the generation id increments on rebalance based on the JoinGroupResponse.
