> Currently user-defined aggregate functions must have one parameter.
> SqlAggFunction need new constructor to set paramTypes to allow user-defined aggregate function to have more than one parameter.
> If a class(A) implement interface of AggregateFunction,that instance of class will be transformed to instance of  SqlUserDefinedAggFunction by call toOp method in CalciteCatalogReader.
> when construct the SqlUserDefinedAggFunction  instance will set paramTypes to null for super class sqlFunction indirectly.
> The problem is:
> we will  get SqlUserDefinedAggFunction paramTypes to sql validatefilte,but it will be filter nothing
