Survey code to see if more fate updates could be done in a single conditional mutation

**Is your feature request related to a problem? Please describe.**

The changes related to #5097 updated seeding a fate transaction to be done in single conditional mutation. There may be other places in the code where this kind of change could be made.

**Describe the solution you'd like**

After #5127 is merged survey the code and look for other places in Fate that can be updated in a single zookeeper or conditional mutaiton update. Then modify the code to make single update instead of multiple.

After #5127 is merged, compare the Fate code with the single conditional mutation change from #5097. Survey for other places where multiple ZooKeeper or conditional mutation updates can become one update, then modify the applicable paths. Done means the identified opportunities are updated without changing behavior.
