Autho dagify aiida plugins

[khsrali]

All aiida calcjobs and workchains should be detected automatically and dagified during the installation

So instead of a script please use a class like bundles/aiida_dag_bundle.py. This one needs to be put into the airflow.cfg and is then automatically called when airflow serializes.

dag_bundle_config_list = [
      {
        "name": "dags-folder",
        "classpath": "airflow.dag_processing.bundles.local.LocalDagBundle",
        "kwargs": {}
      },
      {
        "name": "aiida_dags",
        "classpath": "airflow_provider_aiida.bundles.aiida_dag_bundle.AiidaDagBundle",
        "kwargs": {}
      }
    ]

Then I would use the entry points every aiida workflow already provides
