KAFKA-5263: Avoid tight polling loop in consumer with no ready nodes
If all brokers are unavailable, consumers using manual assignment poll in a
tight loop with no channels to poll from. Producers and consumers using group
management avoid this since they wait for metadata which attempt to create new
connections with any necessary backoff. This PR does a similar wait for
consumers using manual assignment when no nodes are ready.
