Rationale for this change
When using the Datafusion in the distributed engine, Ballista, a session will be created at the server side. While for the client, it will get a session id as the response. Then the client and the server will communicate with each other with specifying the session id as the key for the session state. Therefore, it's necessary to create a session state with specifying a session id at the Ballista client side.
