    Attachment: TAJO-494.patch

This is the first draft.
More tests and improvements for TajoCli are required.
If someone leave some comments, I'll reflect them to my ongoing works.
Welcome any suggestions!

PS. Currently RB looks to be down. I'll submit the patch later.

> In some OLAP applications which has a separate query engine such as Tajo, they accept
SQL-like languages and parse them to generate query plans. Mondrian is a representative example
of these applications. If TajoClient accepts query plans of the JSON form, user queries can
be efficiently executed without the duplicated parse phase.
