Provide documentation how to configure various storage backends

[roeap]

Description

While the "build-in" backends adopt the configuration of object_store and we could always refer to the config over there, we should add some docs in the delta-rs documentation at least pointing folks in the right direction.

Specifically the S3 integration can be adopted to work with several other implementations, sometimes leveraging features (atomic rename) not available in "vanilla" S3.

Use Case

Users should easily discover how they can leverage their storage backend.
