✨ Environment Variables for configuration

[SchweGELBin]

Description

Hello, it would be awesome to be able to set env vars to configure the service.
This would be especially useful for systemd services to run this web-app with small differences to the default config.
This would allow you to have multiple configs for different services and is just a general useful feature.

The environment variables should have a higher priority than the config file if provided.
They could look like this: WEBSURFX_PORT=1234 or WEBSURFX_REDIS_URL=redis://127.0.0.1:1235

Have a great day!

Thanks ❤️ for taking the time to open this issue because this really helps improve the project. So we really appreciate it 👍 .

Good suggestion, but the concerning factor is that environment variables can be quite unsafe compared to config files because with config files you can restrict it like using permissions, groups, different accounts, etc but environment variables cannot be secured in anyway, also, if an attacker gets hold of it and overwrites its value, well then you know all sorts of weird things to expect then. 😅

But I would still like to know @spencerjibz, @jfvillablanca and others suggestion on this?
