public Duration addMeasurements(Load load, int count)  {
        return addMeasurements(load, 0, true, true, count);
    }
Adds measurements with the given resource value and ideal values for the other resources,
scaled to take one node redundancy into account.
(I.e we adjust to measure a bit lower load than "naively" wanted to offset for the autoscaler
wanting to see the ideal load with one node missing.)
