      Description

      We use `InetSocketAddress.getHostName` in `Cluster.bootstrap` and `SocketServer` This call can cause a reverse DNS look-up if an IP address is used in the configuration. `getHostString` avoids the reverse DNS look-up.

      `InetAddress.getHostName` has the same issue and it's used in `SaslChannelBuilder`, `SslChannelBuilder` and `ZookeeperConsumerConnector`. I am not changing these because the the former two actually require the FQDN while the latter is on its way to deprecation.
