Review Comment:
I tried to test the PR, but I'm getting a NPE on line 731
(`newAlert.setDataCenterId(dataCenter.getId());`) because `dataCenter` is null
when the `alertType` is `ALERT_TYPE_MANAGEMENT_NODE`
```

I checked that it was not introduced by this PR, but #9873. However, could
you fix it alongside the refactoring and target 4.20? @hsato03
