Register the cluster server with the master server

[Makosai]

• Send a ClusterSetup::Init to the Master Server with the length + version number as a string and the length + key name as a string as well.
• Send a ClusterSetup::AnswerSecret when receiving a ClusterSetup::Init from the Master Server. It should send back the decrypted passphrase. No length is required because it should be a fixed length anyways (20 characters). IP, port, max connections, and length + name also required.
• If the cluster receives the AnswerSecret command back, that means its a success. Otherwise it fails and the server should not try again. Maintain a connection with the Master Server afterwards if successful.
• If successful, it should try reconnecting to the Master Server on a lost connection.
