KAFKA-6326: when broker is unavailable, fast revover
- when broker is unavailable(such as broker's machine is down), controller will wait 30 sec timeout by dedault. it seems to be that the timeout waiting is not necessary. It will be increase the MTTR of dead broker .
In while loop, pending disconnection and aborted sends got some chances to be processed in client.poll. I am not sure if it's okay to completely skip these cleansing parts.
