Add Scality as an S3 provider covering both Scality RING (S3 Connector)
and ARTESCA, which share the same CloudServer + Vault S3 implementation.
The only quirk required is force_path_style: both products support
path-style addressing, and virtual-hosted style needs wildcard DNS that
on-prem deployments usually lack.
