> {{ZookeeperDiscoveryImpl#cleanupPreviousClusterData}} can delete alive node of a client
in case of low internal order.
> Steps to reproduce: 
> 1. Start server and client.
> 2. Stop the server and wait for the client disconnected.
> 3. Start and stop the server. The server hasn't time to process client join request.
> 4. Start server. It will delete alive client node because the client has low internal
order. The client will never connect.
