text: Title: Metadata for configuration data point
  Body: Hey friends,
  does Dynaconf support metadata alongside it's managed configuration? How would one go about adding further details about a data point? Examples would be the owner or source of a setting, range and restrictions, or a short description for UI explanation.
  
  For my specific use case (data science lab work) I would prefer metadata alongside the value, however I can see that for many production software this might probably find its way into another related file in parallel. 
  
  Is there any support for metadata in the context of Dynaconf or would you guys have a recommendation for a best practice solution? Thanks!
