fix(database_query_utils): make PartitionRowsValidationEvent contains diff between before and after state

[dkropachev]

When there is difference test ends with following message:

sdcm.sct_events.events_analyzer.TestFailure: Got critical event: (PartitionRowsValidationEvent Severity.CRITICAL) period_type=one-time event_id=318ca98d-c349-4cad-bddc-889918d9f326: message=Row amount in partitions is not same before and after running of nemesis: {0: 5555, 2: 5555, 5: 5555, 7: 5555, 8: 5555, 11: 5555, 12: 5555, 13: 5555, 14: 5555, ....}

Which does not tell you what is the difference.
