DependsOn (Java EE 8)

```
@Target(TYPE)
@Retention(RUNTIME)
public @interface DependsOn
```
Used to express an initialization dependency between singleton components.
The container ensures that all singleton beans with which a singleton has a DependsOn relationship have been initialized before the singleton's PostConstruct method is called.
During application shutdown the container ensures that all singleton beans on with which the singleton has a DependsOn relationship are still available during the singleton's PreDestroy method.
