Class EurekaHealthCheckHandler

Computes the Eureka InstanceStatus from all of the Steeltoe Health contributors registered for the application. When this handler is added to the container it registers with the DiscoveryClient as a IHealthCheckHandler. The DiscoveryClient will then call it each time it is computing the InstanceStatus of the application.
