Description

We should introduce a method that takes a class of UDF instead of an instance similar to:

TableEnvironment#createTemporarySystemFunction(String name, Class<? extends UserDefinedFunction> functionClass);

The API should look like:

public static ApiExpression Expressions:call(Class<? extends UserDefinedFunction> function, Object... arguments)

Important: Update the javadocs in *Table as well.
