docs: Setter method for routing_system, mapped from YANG variable /routing_system (container)
      If this variable is read-only (config: false) in the
      source YANG file, then _set_routing_system is considered as a private
      method. Backends looking to populate this variable should
      do so via calling thisObj._set_routing_system() directly.
