## Rationale for this change In our project, we have several UDTFs that depend on the session from which they are called -- for example, functions to list views, tables, etc. To implement them, we need a way to provide the current session state to the UDTF. It would be nice to add the session as an argument to the UDTF call. ## What changes are included in this PR? 1. Introduce `TableFunctionImpl::call_with_args`: it takes struct `TableFunctionArgs`, doing arguments extendable without breaking backward compatibility. 2. Deprecate `TableFunctionImpl::call`. 3. Switch to `call_with_args` for each UDTF in DF. 4. Add an example of the UDTF `table_list()` that depends on the session state. -- This is an automated message from the Apache Git Service.
