Allow to configure the Delta UOMs in PSE
With the introduction of the property "Delta UOM", there is no way to control this in PSE. We need this to properly configure or modify UOM classes
Refer to 2017SP2 release notes:
A new property, DeltaUOM, has been added to the UOM object to allow applications to determine the appropriate unit for measuring the differences between two values. For example, temperature units typically have a different unit to represent deltas because of the offset present in the conversion factors.
