[Feature Request] Add an option to send all log messages to a file [PR welcome]

[lollingtonbear]

I would like an option to send all log messages to a file.

The logs don't appear in journal and there doesn't seem to be a log file, it just outputs to pythons stdout.

I run decluttarr as systemd service, and I've tried using common methods to direct output to a file but the file remains empty. Assuming the issue is not just me being crap, I'd like an option to output log messages to file.

Hi @lollingtonbear
Thanks for bringing up the idea. I am a little bit stretched these days and wont be able to do it, but happy to review a PR if you‘d like to contribute

Some pointers, where I think you'd need to changes:

• config/config.conf-Example -> Add a new parameter "LOG_FILE_OUTPUT" boolean
• config/definitions.py -> Load the LOG_FILE_OUTPUT (probably under "General")
• src/loadScripts.py -> add to the def showSettings(settingsDict) the new LOG_FILE_OUTPUT
• src/main.py -> where "Set up logging" is written, add another handler if LOG_FILE_OUTPUT is true, which then outputs to a file. You may need to think of file rotation to prevent that the files become too large
• README.md
  -> Add the new parameter to the docker-compose example, and explain the new LOG_FILE_OUTPUT under "Explanation of the settings"/"General"
  -> Specify the folder that needs to be mounted in docker-compose so that from the hosting system the logs can be seen. Example:

   volumes:
     - $DOCKERDIR/appdata/decluttarr/logs:/logs

Thanks. While I can code, (Java, Bash, Powershell, Pascal (I'm old)) I've not tried Python. This could be a good way to get started.
