find an error in the tutorial

[Duncan-tree-zhou]

in the tutorial http://wurstmeister.github.io/kafka-docker/ use the following example:

$KAFKA_HOME/bin/kafka-console-consumer.sh --topic=topic --zookeeper=$ZK

but actually --zookeeper is not an option for kafka-console-consumer.sh. it should be replace by option --boostrap-server. please correct it.

--zookeeper

I thought --zookeeper is deprecated as per the help menu.

[Duncan-tree-zhou]

That doesn't mean it's removed yet.

I had checked kafka official doc. the zookeeper.connect config for consumer api is deprecated in ver 0.10.0 (kafka doc 0.10.0, tag:consumerconfigs) and removed in ver 2.1.0 (kafka doc 2.1.0, tag:consumerconfigs)

it means that the --zookeeper option would not be supported after ver 2.1.0.

i think to add a tip may avoid some misunderstanding for users.
