Review comment:
Good question, without it the verifiable consumer fails with:
```
usage: verifiable-consumer [-h]
--broker-list HOST1:PORT1[,HOST2:PORT2[...]]
--topic TOPIC --group-id GROUP_ID
--group-instance-id GROUP_INSTANCE_ID
[--max-messages MAX-MESSAGES]
[--session-timeout TIMEOUT_MS] [--verbose]
[--enable-autocommit]
[--reset-policy RESETPOLICY]
[--assignment-strategy ASSIGNMENTSTRATEGY]
[--consumer.config CONFIG_FILE]
verifiable-consumer: error: argument --group-instance-id is required
```
I assumed that this check was added for a reason, however maybe it's being
to strict?
