HIVE-1935 made a start on converting some of our condition helpers to use generics. However, it didn't go far enough to achieve one of the main goals, which would be reduction of redundancy and #LOC. It would be great to dig deeper, e.g. deduplicating funcs like Set<CRDType>Condition[WithChangeCheck] (example).

There's a bit of challenge here because some of these differ slightly: e.g. SetClusterDeploymentConditionWithChangeCheck ends by sorting the conditions.

I wonder if we could manage this by creating an interface with a default no-op impl for the sorting func, which we would override for ClusterDeployment. Not sure how/whether that would dovetail with generics.
