leorochael opened a new pull request #4631: Fix flower broker configuration
URL: https://github.com/apache/incubator-superset/pull/4631
 
 
   In case the celery broker is configured with transport options, these options would not be passed into flower with a --broker parameter.
   
   A clear example is that, when launched with `superset flower`, the `superset.sql_lab.get_sql_results` task was not reported by flower on startup:
   
   ```
   2018-03-16 16:57:37,208:INFO:flower.command:Registered tasks: 
   ['celery.accumulate',
    'celery.backend_cleanup',
    'celery.chain',
    'celery.chord',
    'celery.chord_unlock',
    'celery.chunks',
    'celery.group',
    'celery.map',
    'celery.starmap']
   ```
   
   More importantly, flower could outright fail to work if a broker with less usual options was configured by superset, since these options were not passed at all into flower.
