Review Comment:
Can we replace `if` with class-dependent logic here?
For example
```
this.stateBackendName = checkpointStateBackend.getName();
this.stateChangelogEnabled =
TernaryBoolean.fromBoolean(
StateBackendLoader.isChangelogStateBackend(checkpointStateBackend));
```
Where `getName()` by default returns `this.getClass().getSimpleName()`,
and changelog returns `delegatedStateBackend.getName()`?
