Cleaning up an offline defunct server

If you have removed a defunct server and want to keep it as a standalone server, then you also need to run the remove-defunct-server --performLocalCleanup command on the defunct server while it is offline. This will remove all topology configuration references on the offline server, and make it a standalone server. This is useful if a server is temporarily misbehaving, but you want to add it back to the topology at a later time. The remove-defunct-server command will only accept the --performLocalCleanup argument if the server is offline.
