> Currently, 
> V2ExpressionBuilder will build connector.Cast expression from catalyst.Cast expression.
> Catalyst cast have expression data type, but connector cast does not have it.
> Since some casts are not allowed on external engine, we need to know source and target data type, since we want finer granularity to block some unsupported casts.
