// NodeToolCli does not extend LoggingAwareCommand, because LoggingAwareCommand performs logging initialization
// after LoggingAwareCommand instance is constructed.
// It's too late for us, because before UnsafeBootstrapMasterCommand is added to the list of subcommands
// log4j2 initialization will happen, because it has static reference to Logger class.
// Even if we avoid making a static reference to Logger class, there is no nice way to avoid declaring
// UNSAFE_BOOTSTRAP, which depends on ClusterService, which in turn has static Logger.
// TODO execute CommandLoggingConfigurator.configureLoggingWithoutConfig() in the constructor of commands, not in beforeMain
