S3-compatible object storage for file-uploads

[Znuff]

Feature Description

It would be very nice if we could get support for file-uploads to go directly to an s3-compatible object storage.

As for motivation, I run TheLounge on a low-powered/low-storage machine in my network, which is only directly accesible via a VPN.

I really like the idea of having file-uploads, and, well, file uploads are only useful if other people can click the links I post.

S3-compatible object storage is ubiquitous at this point, and there's plenty of libraries available on the market.

S3-compatibility would allow us to use plenty of services on the market:

• Cloudflare R2
• Backblaze B2
• MinIO
• others

Hopefully the plugin system (#1422) will:

• Be completed someday
• Include hooks for things like file and message storage

Different object-storage backends are squarely in "plugin territory" as I interpret the maintainers' vision. The limitation right now is that the core doesn't yet have a way for plugins to provide alternative storage backends.

Basically, if you would like support for something like this, I recommend voting up #1422. I've already noted that the handy summary of desirable plugin APIs there doesn't yet include file uploads.
