If you use ```entrySet()``` instead of ```keySet().iterator()```, test

> TajoShellCommand::getUsage() is designed for TajoShellCommand::printHelp() to
> printout detailed-usage like TajoShellCommand::getDescription(). But,
> Currently, It's omitted in TajoShellCommand::printHelp(), so
> TajoShellCommand::getUsage() has no usage.
