Proposal: Switch to R2 for large file hosting

Proposal: Switch to R2 for file hosting.

R2 is a drop-in replacement for S3 sold by cloudflare.

R2's big advantage is ease of setup, and more particularly ease of setting up access credentials.

R2 does not use IAM's instead, you can create API credentials. Here's what that looks like:

Click create gives you credentials that you can use everywhere boto or any other client expects AWS credentials.

Disadvantages

• The current s3-credentials pattern has already made it a lot easier to set up credentials for s3 then it used to be. Even though r2 is a easier, it may not be a big enough difference.
• We have a lot of legacy s3 buckets set up which we are not really going to convert. so we will have to use two tools for a long time.

The linked s3-credentials patterns seems to be sufficient. And it's best to not have two different s3 providers.
