 * This delagates actual execution to {@link #runWithUrl(String)} and handles any
 * Spring Rest exceptions, wrapping them as necessary. Default behavior is to throw
 * a {@link RetryableApiCommandException} for 5xx errors and timeouts, and {@link
 * NonRetryableApiCommandException} for all others. If you need different behavior
 * your best bet is to write your own {@link RemoteServiceCallback} and/or use
 * the various flavors of {@link org.springframework.web.client.RestTemplate} that
 * take let you provide {@link ResponseErrorHandler}.
 * @param url The URL of the remote service.
 * @return Result of the remote call, or potentially throws an exception if an
 * error occurs calling the remote service.
