[KAFKA-10233] KafkaConsumer polls in a tight loop if group is not authorized

Description

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.
