Pierre Villard resolved NIFI-10573.
-----------------------------------
    Fix Version/s: 1.25.0
                   2.0.0
         Assignee: Pierre Villard
       Resolution: Fixed

Resolved by NIFI-12587 and NIFI-12593.

To get the error for all invalid lines, an option is to have ValidateCSV that splits the flow file into a valid flow file and an invalid flow file, and have the invalid flow files split with one line per flow file and get the data through another ValidateCSV so that each line can have the proper error message with the reason why the line is invalid.

> ValidateCsv should generate more descriptive error messages because the current ones do not provide what column/field failed the validation. A nice idea would also be to create a companion error file (on a separate relationship) that would contain validation errors for all the failed lines.
