Hi,\nI am trying to add a celery task with the help of documentation.\n\n```CELERYBEAT_SCHEDULE = {\n        'cache-warmup-hourly': {\n            'task': 'cache-warmup',\n            'schedule': crontab(minute='*/5'),  # @every 5 min\n            'kwargs': {'strategy_name': 'dummy'},\n        }```\nI added above in config file but there isn\u2019t any celery task registered. I also not getting anything in `superset/tasks/schedulers.py`  file. Can anyone help me in triggering this cache-warmup task?
