@dmpe , I see you opened this draft PR - thank you for working on this enhancement.

Before you go too far into implementing it, I'm wondering if it's a good idea to adopt a more generic approach where one can specify an array in something like .Values.csiNode.image.nodeDriverRegistrar.additionalArgs and have Helm template modified to append these additional arguments. This way it's possible to pass any arbitrary arguments and not just --logging-format=json.

EDIT 1: wait, one more adjustment...
EDIT 2: ready for review
