docs: Configures the interface shutdown state
  
          Default configuration for set_shutdown is disable=True, meaning
          'no shutdown'. Setting both default and disable to False will
          effectively enable shutdown on the interface.
  
          Args:
              name (string): The interface identifier.  It must be a full
                  interface name (ie Ethernet, not Et)
  
              default (boolean): Specifies to default the interface shutdown
  
              disable (boolean): Specifies to disable interface shutdown, i.e.
                  disable=True => no shutdown
  
          Returns:
              True if the operation succeeds otherwise False is returned
