TAJO-762: Implements current date/time function
I rebased after committing TAJO-825.
While running TestCase I found the next message, but all tests is succeeded.
This message is generated in the TestBuiltinFunctions.testRandom() because
every random() eval makes different value.
So I fixed TajoClient.executeQueryAndGetResult() method, some test codes
and removed TestBuiltinFunctions.testRandom() in this patch. I'll create new
issue for TestBuiltinFunctions.testRandom() bug.
