* The main idea to use this - it's adding the ability to start rule nodes in singleton mode in cluster setup

* ENABLE - user doesn't have ability to configure clustering mode (singleton mode is always FALSE in rule node config)
* SINGLETON - user doesn't have ability to configure clustering mode (singleton mode is always TRUE in rule node config)
