/**
 * Override method from {@link com.netflix.client.AbstractLoadBalancerAwareClient} because it constructs
 * a {@link RibbonLoadBalancerClient.RibbonServer} that is not fit for our use. Namely, it's getUri() method always returns http scheme, causing the
 * retryable client to always call http. We have stored the instance info from the load balancer in the context
 * so we recreate EurekaServiceInstance here, which correctly resolves whether instance is http or https when asked.
 * @param serviceId
 * @return EurekaServiceInstance
