Expose Model Predictions from `diskprediction_local` module

Hi team,

I'm a data scientist on the AICoE team. Some time back, we had added failure prediction models to the `diskprediction_local` module in ceph upstream ([PR](https://github.com/ceph/ceph/pull/29437)). Would it be possible to expose predictions from these models on the "devices" grafana dashboard in some way?

Basically, we want to ensure these predictions make their way to users / SMEs / open source community, so that they can provide us some feedback. This feedback would be incredibly valuable for improving existing models, and also for better understanding if the kind of output we're providing is useful or is there something better that we can provide. Let's have a discussion here :)
