Improve logging

[gatepoet]

Logging is currently done with log files using NLog. I propose that we switch to using console logging. It would also be preferable to have the logging configuration as a docker config in order to change the logging level at runtime. This way we don't have to re-deploy the web server just to change the log-level

When you say "log level", that means "debug", "production" and similar? I can't imagine it will be important to switch between them runtime - or will it?
Another thing: "console loging" - that means output goes to the console, right? Isn't that awkward? (But of course: you don't have to get rid of old log files, and that is a pro..)

What does it cost resource-wise? Is it a big job to switch?
