This patch creates new package 'plan/validator'. But, it's duplicated to
'plan/verifier'. So, I moved the classes to 'plan/verifier'.
> LogicalPlanVerifier should check not supported type in file formats

>
> *Problem*
> There are a variety of file formats in Hadoop eco systems. BTW, they have
> different type supports. For example, RCFile supports DATE type, but Parquet
> does not support DATE. Users can use not supported data types in a specified
> file format for writing tables.
> But, current Tajo does not check available data types for each file format.
> So, if a user specifies not supported types in his table for writing, a
> runtime error will occur while a query is running.
> *Solution*
> We should check not supported data type in logical plan verification phase.
