feat: add filename to deployments db

[PatrickAlphaC]

What I did

add a filename column to the database

How I did it

class DeploymentsDB:
    def __init__(self, path=":memory:"):
        if path != ":memory:":  # sqlite magic path
            path = Path(path)
            path.parent.mkdir(parents=True, exist_ok=True)

        # once 3.12 is min version, use autocommit=True
        self.db = sqlite3.connect(path)
        self.db.execute(_CREATE_CMD)

        # Migration for legacy DB without filename column
        if not self._filename_is_in_db():
            try:
                self.db.execute("ALTER TABLE deployments ADD COLUMN filename text;")
                self.db.commit()
            except sqlite3.Error as e:
                self.db.rollback()
                raise Exception(f"Failed to add 'filename' column: {e}")

How to verify it

You can run the test I created:

pytest -k test_deployments_db_migration
