      Description

      (I've changed this issue from implementing an utility class to preint JSON to implementing EXPLAIN clause support.)

      For convenience for debugging and developing new engine (TAJO-104), we need EXPLAIN clause to print plans used in Tajo internal. In this issue, we only focus on showing a logical plan.
