The percentage metrics currently are either relative to the actual, or relative to the mean of actual and forecast (symmetric).

A parameter should be added that also allows to normalize by the forecast only, e.g., by introducing an argument relative_to that is by default "y_true".

Update: this has been implemented for the functions in #8266.

It should now be added to the classes, with same argument.
