This commit adds versioning to the serializedDagModel. Changes: Added new columns, id, and version_number to the SDM and made id the primary key. Updated the write_dag method of the SDM to add the SDs correctly. Updated the queries so the scheduler/webserver runs with the latest SDM The version_number was added to help us track the evolution of a DAG. Suppose a DAG with dag_hash AB is changed, and the dag_hash becomes CD. If the change is reverted, we will have a dag_hash of AB again. In this case, the version_number would still increment, letting us know that the DAG was changed three times. I feel it's a meaningful way to track the changes, independent of the id column, which is database internals.
This helps to track the serialized DAG version the task instance ran with by establishing a relationship between the entities instead of using the dag_hash.
