   For now, in S3 backend, `operator.create_dir("test/")` would create a empty object, with key `test/`. Which might cause a lot of problem.
   
   For example:
   
   ```
   use opendal::Operator;
   
   #[tokio::main]
   async fn main() -> anyhow::Result<()> {
       let mut builder = opendal::services::S3::default();
       builder.endpoint("http://localhost:9000");
       builder.access_key_id("minioadmin");
       builder.secret_access_key("minioadmin");
       builder.region("us-east-1");
       builder.bucket("test");
       let operator = Operator::new(builder)?.finish();
       operator.create_dir("test/").await?;
       
       // List method required path ends with '/'.
       let mut lister = operator.list("test/").await?;
   
       // Given dir would not in the list.
       assert_eq!(lister.next_page().await?.unwrap().is_empty(), true);
       Ok(())
   }
   ```
