> MiniZookeeperCluster.shutdown() shuts down the ZookeeperServer and NIOServerCnxnFactory.
However, MiniZookeeperCluster uses a deprecated ZookeeperServer constructor, which in turn
constructs its own FileTxnSnapLog, and ZKDatabase. Since ZookeeperServer.shutdown() does not
close() the ZKDatabase, we have to explicitly close it in MiniZookeeperCluster.shutdown().
