title: Dynamic configurations refresh for a python application
body: <p>I am developing a python application (in a SaaS model), using flask framework and some simple worker applications which consume messages from some message bus.
  for those type of services I would like to use some dynamic configurations which don't involve container restart but refresh automatically.</p>
  
  <p>(by saying dynamic configuration - those configurations can be set on some DB and there could be a thread which check for changes and update those configurations in a time of need - those configurations are dynamic and not environment variables)
  is there some kind of open source which do it?</p>
  
  <p>Thanks in advance</p>
