I am a bit confused here, this seems to make things more complicated.
Before, if you wanted to use ZK and Kerberos, you only added `zookeeper` to
`security.kerberos.login.contexts`. Now you need additionally to set
`zookeeper.sasl.disable` to `false`?
Why don't we keep `zookeeper.sasl.disable` as `false` by default? If I
understand it correctly, it is anyways only ever relevant when the ZooKeeper
login context has been enabled...
