For all the commands that call Initialise, we introduce a new flag: UseSequential. This disables DAG scheduling for evaluating datasources and locals as a fallback to the newly introduced DAG scheduling approach. `hcl2_upgrade` is a special case here, as the template is always JSON, there cannot be any datasource, so the DAG in this case becomes meaningless, and is not integrated in this code path.
