some config updates for ml (#12771)

- set `dbengine anomaly rate every` to 30 by default to provide better sorting functionality for anomaly advisor.
- increase upper clamp on `MaxTrainSamples` to 24 hours for those who might like a larger training window on a parent.
- decrease lower clamp on `MinTrainSamples` to 15 minutes to enable faster training of initial models.
