docs: In the case where you have accessed an existing health check on a
          load balancer, this method applies this instance's health check
          values to the load balancer it is attached to.
  
          .. note:: This method will not do anything if the :py:attr:`access_point`
              attribute isn't set, as is the case with a newly instantiated
              HealthCheck instance.
