Add AnomalyDetectionPolicy

AnomalyDetectionPolicy contains all the knobs for anomaly detection. Since Robolectric doesn't support KeyValueListParser, this cl creates KeyValueListParserWrapper so we could mock it and test AnomalyDetectionPolicy Bug: 36924669 Test: RunSettingsRoboTests Change-Id: I71138f85d37a21b5c4c9c806a41e00a4aa924f5f
