Add command line switch --production to not render swagger endpoints

It's called --production as we might add more things in the future that are disabled in production runs. We could also enable logging sensitive things like access token in non-production runs.

I'm not super happy. In general I think software should be in production mode. Debug/Developing features need to be enabled manually/explictly. And not the way otherway. What do you think about:

• reversing logic: --development (enables swagger, default is off)
• --enable-swagger instead of using it --production/--development - I don't know if there are more things to come in the future that are turned on/off
