quarkus.application.name is not taken into account in stop message
If I add this to my `application.properties`:
```
quarkus.application.name=MyApp
```

Startup message is OK:
```
2019-10-10 14:39:15,327 INFO  [io.quarkus] (main) MyApp 1.0-SNAPSHOT (running on Quarkus 999-SNAPSHOT) started in 0.612s. Listening on: http://0.0.0.0:8080
2019-10-10 14:39:15,333 INFO  [io.quarkus] (main) Profile prod activated. 
2019-10-10 14:39:15,334 INFO  [io.quarkus] (main) Installed features: [agroal, cdi, narayana-jta, resteasy, security, security-jdbc]
```

But not the shutdown message:
```
^C2019-10-10 14:39:17,713 INFO  [io.quarkus] (main) Quarkus stopped in 0.029s
```

We should fix the shutdown message to be consistent.

Also we need to find a place to document this feature properly. But I couldn't find an obvious place.
