Problem: Adding S3 storage support requires editing config files

[jorgesat]

Covers, avatars and other media attachments often consume a lot of space. It would be more convenient to store them as S3 objects using third party providers. However, configuring S3 requires editing the .env.production file. To improve this configuration process, I suggest to add a section to the Administration settings where the S3 storage support can be configured by admins.

I agree that such a change should be possible without editing configs. Is there a data migration process that needed to go along with the config change?
