ApplicationStartupListener (dropwizard-guicey 5.9.2 API)

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
```
@FunctionalInterface
public interface ApplicationStartupListener
```
Dropwizard application complete startup listener. Useful for delayed code execution after server startup. Supposed to be used instead of ServerLifecycleListener (because server listener is not called for guicey lightweight tests) and instead of LifeCycle.Listener in cases when only startup event is important (easier to use).
It also receives application injector to simplify usage.
