> Currently the connection status analytics object is tightly coupled with the type of
model used for prediction. This should be refactored to allow flexibility for model selection.
Users should also be able to configure the model used via nifi.properties as described below:
>  
> nifi.analytics.connection.model=org.apache.nifi.controller.status.analytics.models.OrdinaryLeastSquares
> nifi.analytics.connection.model.score=rSquared
> nifi.anlytics.connecttion.model.score.threshold=.90
>
