@kba should I make a v2 backport of 0d277ac?

I should probably create an issue for this, but perhaps someone can get me on track here: Shouldn't we also allow the user to pass the ocrd_utils.config options to the server, somehow? (In v3, you'll remember, we introduced fine-grained controls like OCRD_MISSING_INPUT, OCRD_MISSING_OUTPUT, OCRD_EXISTING_OUTPUT, that should in principle be configurable on a case-by-case basis. Without any such delegation, one would have to live with the defaults set on the server side, so there's not much use for them in the network scenario...)
