Fully reloading the configuration without restarting dnsdist is not 
possible, mostly because we made the choice to create some objects at 
configuration time and not at runtime for performance reasons.
You can, however, add and remove downstream servers at runtime without 
reloading dnsdist by using the console [1].

Hope that helps.
