[TASK] Extract relevant parts of JsonRenderer into ext:test_irre_csv

To further separate concerns from ext:irre_tutorial, the configuration
of JsonRenderer looses all parts that only concern the 1ncsv scenario.

Ext:test_irre_csv receives a dedicated JsonRenderer, that is used by
related test scenarios.
