Aliyun OSS support

[linhr]

We need to investigate how to support Aliyun OSS via the object_store interface.

I haven't found a single promising OSS SDK in Rust, so we need some more investigation. The scope of work won't be large though. We can also see how OpenDAL handles it.

See #2209 for accessing Aliyun OSS via s3://. This is a temporary solution with a few limitations.
