Review Comment:
> Agree with move this map to TaskExecutorStateChangelogStoragesManager for
consistent.
I see the two maps are still in different classes (
`StateChangelogStorageLoader.changelogStorageViewsByJobId` and
`TaskExecutorStateChangelogStoragesManager.changelogStoragesByJobId`).
> The current implementation does not consider switching
StateChangelogStorage implementations
IIRC, it **is** possible, after FLINK-23252. Or do you see any obstacles
preventing from switching the implementation?
I don't think it's mandatory though, just want to be on the same page.
