docs: Ask to the arbiter to reload the monitored configuration
  
          **Note** tha the arbiter will not reload its main configuration file (eg. alignak.ini)
          but it will reload the monitored objects from the Nagios legacy files or from the
          Alignak backend!
  
          In case of any error, this function returns an object containing some properties:
          '_status': 'ERR' because of the error
          `_message`: some more explanations about the error
  
          :return: True if configuration reload is accepted
