docs: Send a new configuration to the daemon
  
          This overrides the default method from GenericInterface
  
          Used by the master arbiter to send its configuration to a spare arbiter
  
          This function is not intended for external use. It is quite complex to
          build a configuration for a daemon and it is the arbter dispatcher job ;)
  
          :param pushed_configuration: new conf to send
          :return: None
