Hello @alamb , Here is a draft for #8907 . I am yet to add tests. Currently DefaultObjectStoreRegistry

pub fn new() -> Self {
        let object_stores: DashMap<String, Arc<dyn ObjectStore>> = DashMap::new();
        object_stores.insert("file://".to_string(), Arc::new(LocalFileSystem::new()));
        Self { object_stores }
    }

registers only LocalFileSystem .
I am wondering if it should register other stores as well , like S3, GCS etc.
