Merged HEAD-BUG-FIX (5.1/Cloud) to HEAD (5.1/Cloud)

105991: Merged 5.0.N (5.0.3) to HEAD-BUG-FIX (5.1/Cloud)
      105915: Merged V4.2-BUG-FIX (4.2.5) to 5.0.N (5.0.3)
         105898: MNT-13901 TransformationOptions Timeout Can Not Easily Be Set
            - Fix "TransformationOptionPair.setMax(long max) and TransformationOptionPair.setLimit(long limit) so that they don't
              clear the other half of the pair when the value being set is < 0 (unset).
            - Unit tests added
            - Added comments about how the 'transformer' code builds up limits to include defaults.
