Simple query (non-forwarded query) should be supported against partition tables.

There are two types of queries according to whether a query is executed across cluster nodes or not.

We call a query which is executed across cluster nodes forwarded query, meaning that TajoMaster forwards the query to a query master. In contrast, we call a query without distributed execution simple query or non-forwarded query, which executed in only client side. The following query is an example of simple query.

select * from table limit 10;

Currently, simple query is only supported against a normal table. We also should support it against partitioned tables.
