      Description

      Users affected by poor performance might want to understand how Flink is serializing their data.

      Therefore, it would be cool to have a tool utility which logs the serializers like this:
      SerializerUtils.getSerializers(TypeInformation<POJO> t);
      to get

      PojoSerializer
          TupleSerializer
            IntSer
            DateSer
            GenericTypeSer(java.sql.Date)
          PojoSerializer
            GenericTypeSer(HashMap)
