> Currently, we should use tajo-site in order to change the configurations related queries, such as optimization option or some parameters. It is never practical because we need to restart a Tajo cluster in order to change the config.
> The main purpose of this issue is to refactor the system of session variable and some part to recognize query configs to accept the session variables. Also, when there are duplicated configs in session and TajoConf, session variables should override the existing config of TajoConf.
