Anomalies are now detected and declared per dimension. This means that declareAnomaly now gets access to the key that is responsible for the anomaly. Moreover, the refractory period is per dimension, not overall. So a second anomaly for the same metric but a different dimension can fire within the first dimension's refractory period. Thus, if app A misbehaves and app B misbehaves shortly thereafter, they will both be detected. Eventually this key will be passed to the subscribers, although this cl doesn't do anything with it.
