Structured logging and uploading logs

[Brutus5000]

We need to improve the way we handle logging in the overall architecture.

• User should no longer need to upload their logs manually. With given consent, the logs should be automatically uploaded when before application exits.
• Logs should be structured JSON in order to be efficiently stored and indexed in e.g. Loki
• There should be one log file per game stored on disk.
• We need to give persistent log contexts throughout all logs, so it still can be searched cross-reference on the server, i.e. having the game id and the user id in every single log line.
