Hello.

I'm using S3 Dag Bundle and it works perfectly except one thing. Files removed remotely (in S3 bucket) won't be removed in Airflow. My source S3 bucket contains some config files additionally to dag files. I use these config files to generate dags dynamically like that:

configs_dir = Path(__file__).resolve().parent / 'configs'

for file in glob(f'{configs_dir}/*.yaml'):
  with open(file, 'r') as f:
    config = yaml.load(f)

  # Generate pipeline
  @dag(
    dag_id=config['dag_id'],
    schedule=config['cron'],
    tags=config['tags'],
  )
  def yac_instance_autoshutdown_pipeline():
    ...

So number of dags have to be the same as number of yaml files in configs folder.
When one of the yaml files removed from configs folder it's expected that it will be removed locally too and appropriate dag will be deactivated.
Actual behavior: dags will appear when new config files created, but won't be deactivated when config files removed.

Is there any way to clean up files that were removed on remote S3 bucket? Any workaround would help. Would be best to allow something like --delete flag for S3 Bundle configuration, but currently it is not supported.
