 * The main idea to use this - it's adding the ability to start rule nodes in singleton mode in cluster setup
 * (singleton rule node will start in only one Rule Engine instance)
 * USER_PREFERENCE - user has ability to configure clustering mode (enable/disable singleton mode in rule node config)
 * 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)
