A convenience class for launching a Spring Boot app with retry and backoff if it fails. While the main app is failing the backoff brings up a web endpoint on /actuator/info and /actuator/health. The health endpoint will show as "DOWN" until the main application context comes up successfully.

Usage:

@SpringBootApplication
@RestController
public class StarterApplication {

	public static void main(String[] args) {
		BackoffSpringApplication.run(StarterApplication.class, args);
	}
    
}

(Just use BackoffSpringApplication to run the main method.)
