Detailed Description

The context reset atomically discards all forecasting state, and is used when the monitored filesystem changes.

Metrics and model state from different filesystems must not share the same time series. If the filesystem changes, then we clear the metric, model, forecast, summary and reporting state before accepting samples for the new filesystem.

Preserve the metric count and advance the model so old logical indexes are not reused.

A capacity change (resize) for the same filesystem does not reset the series.
