KAFKA-3645: Fix NPE in ConsumerGroupCommand and ConsumerOffsetChecker
The host and port entries under /brokers/ids/<bid> gets filled only for
PLAINTEXT security protocol. For other protocols the host is null and the
actual endpoint is under "endpoints". This causes NPE when running the consumer
group and offset checker scripts in a kerberized env. By always reading the
host and port values from the "endpoint", a more meaningful exception would be
thrown rather than a NPE.
