Fix for #8753
UpDownCounter and Counter have the same implementation but they are interpreted differently by the .Net OTel SDK. UpDownCounter supports reporting negative values and is suitable to keep track of the number of active grains per type. The metric will be exported by the OTel SDK as a cumulative value instead of a delta for Counter.
