What would you like to be added or enhanced?

Today Iceberg is provided through S3 Tables integration, specific to AWS. The ask is to add additional providers, or a way to specify any S3 bucket.

For example Cloudflare R2 Data Catalog is designed for this use case.

Why is this needed?

Iceberg is growing in popularity as a datalake format, and so are the ways that folks want to. It would be great to be able to publish to any provider instead of just AWS.
