initialize_enforcer with other DB_ALIAS about django-orm-adapter

@BustDot the DB name should be customizable in the constructor function, this feature should be supported. See other adapter as example: https://github.com/pycasbin/pymongo-adapter#simple-example

I will look into it.

The django docs illustrate how to use another databases.

Since the django-orm-adapter uses the default databases, you can add a database argument for the adapter and change the code whenever interacting with the django-orm.

For example(I'm not sure whether it is correct, just for demonstration):

def save_policy(self, model):
        """saves all policy rules to the storage."""
        # See https://casbin.org/docs/en/adapters#autosave
        # for why this is deleting all rules
        CasbinRule.objects.using("account").all().delete()

        lines = []
        for sec in ["p", "g"]:
            if sec not in model.model.keys():
                continue
            for ptype, ast in model.model[sec].items():
                for rule in ast.policy:
                    lines.append(self._create_policy_line(ptype, rule))
        CasbinRule.objects.using("account").bulk_create(lines)
        return True
