Change validate methods to not have any params

[MoonBow-1]

Description

Validate methods should validate self, and not be dependent on outside parameters

[MoonBow-1]

Example of old isValid/validate method:

public boolean isValid(final Configuration configuration) {
         boolean valid = true;
         final FaultyReport faultyReport = new FaultyReport();
         ...

         try {
             faultyReport.writeFaultyRecords(configuration.faultyReportFile);
         ...

Refactored version:

class Example {
     final FaultyReportFile faultyReportFile;
     ...
     public boolean validate() {
         boolean valid = true;
         final FaultyReport faultyReport = new FaultyReport();
         ... 

         try {
             faultyReport.writeFaultyRecords(faultyReportFile); 
         ...
}
