------------------------------------------------

The PR didn't get any updates for a while. Postponing for the next release but let me know if it can still be merged to 3.0 before code freeze.

> Consumer propagates GroupAuthorizationException from poll immediately when trying to find coordinator even though it is a retriable exception. If the application polls in a loop, ignoring retriable exceptions, the consumer tries to find coordinator in a tight loop without any backoff. We should apply retry backoff in this case to avoid overloading brokers.
