feat: harmonize and simplify storage configuration (delta-io#1052)

# Description
Recently we moved some of our storage configuration via a property bag
upstream to the object_store crate. This allows us to simplify our
configuration handling here and make S3 configuration consistent with
azure and gcp.

I think as a follow up it would be great to migrate dynamodb_lock to
using the official SDKs as well, and then see what we still need form
the s3 storage options.
