Add a new forecasting pipeline that does scale - forecast - unscale

[rtavenar]

This PR builds on PR #700

This PR aims at implementing #708

At the moment, we only tackle scalers that have their inverse_transform method covered in #700, but ideally we would like to cover the per_timeseries=True also at some point since this is common practice in modern forecasting pipelines to do the scaling per time series.
