> Add genericUDF/reflectUDF that will allow users to use methods from Java directly, instead having to write a UDF wrapper on top of existing Java method.
> *Usage:*
> {code:sql}
> SELECT reflect("java.lang.String", "valueOf", 1),
>        reflect("java.lang.String", "isEmpty"),
>        reflect("java.lang.Math", "max", 2, 3),
>        reflect("java.lang.Math", "min", 2, 3),
>        reflect("java.lang.Math", "round", 2.5),
>        reflect("java.lang.Math", "exp", 1.0),
>        reflect("java.lang.Math", "floor", 1.9)
> FROM src LIMIT 1;
> 1   true    3   2   3   2.7182818284590455  1.0
