InitializingService (Hekate 4.0.0)

All Known Subinterfaces:

CoreService
```
public interface InitializingService
```
Lifecycle interface for services that require initialization.
Methods of this interface get invoked when Hekate instance starts joining the cluster.

Invocation order is:
1. preInitialize(InitializationContext) all services one by one
2. Await for ClusterContext.onJoin(int, Set) notification from the cluster service
3. initialize(InitializationContext) all services one by one
4. postInitialize(InitializationContext) all services one by one
Note: Initialization order takes dependencies into account. If some service A depends on some other service B then it is guaranteed that initialization methods of service B will be called prior to initialization methods of service A.
