Support of S3 backend

[vgnx]

Hi 👋,

I'm trying to setup runrestic to push my backup in S3.
By reading the sample config file, it's not clear to me in you support all environments variables or only RESTIC_PASSWORD and RESTIC_PASSWORD_FILE` ?

The schema.json file into your code let me think it's not supported by I prefer to ask.
If it's not supported, do you plan to do so ?

any key that you set in [environment] will be added to the environment

Thank you for your answer.
It's probably a miss configuration from my side. I'll check
