      Description

      Currently we block indefinitely in poll() when discovering the coordinator for the group. Instead, we can return an empty record set when the passed timeout expires. The downside is that it may obscure the underlying problem (which is usually misconfiguration), but users typically have to look at the logs to figure out the problem anyway.
