SlingRepositoryInitializer (Apache Sling 9 API)

```
@ConsumerType
public interface SlingRepositoryInitializer
```
All active SlingRepositoryInitializer services are called before making the SlingRepository service available, and can perform initializations on it, like creating service users, setting up initial access control, migrating content in upgrades, etc. The SlingRepositoryInitializer services need to be aware of any repository clustering scenarios as well as multiple Sling instances accessing the same repository. They might need to implement locking to avoid conflicts.
