KAFKA-8792; Default ZK configuration to disable AdminServer
Kafka ships with default ZK configuration. With the upgrade to ZK 3.5, our
defaults include running ZK's AdminServer on port 8080. This is an unfortunate
default as it tends to cause conflicts.
I suggest we default to disable ZK's AdminServer in the default ZK configs
that we ship. Users who want to use AdminServer can enable it and set the port
to something that works for them. Realistically, in most production
environments, a different ZK server will be used anyway. So this is mostly to
save new users who are trying Kafka on their own machine from running into
accidental and frustrating port conflicts.
