[FIXED JENKINS-24006] Changes to healthScaleFactor were not actually being saved.
Ripping out the archaic manual form binding code and replacing with the modern simplified scheme.

So there should be no problem releasing 1.2.
AggregatedTestResultPublisherTest and perhaps other callers of deprecated constructors might be passing null for testDataPublishers.
Avoid deprecated constructors.
