If you don't mind changing all 15 implementers of
ConfigurationUpgrade, you could add a method to that interface that
returns a priority, and then sort the list that is returned by
getInhabitants before running them.

I need to do this in the admin/config-api package, so I can't use one of the method that takes a Class without using reflection (we don't want the config-api package to depend on gms-adapter).

I know other classes can inject an instance of it to make sure it runs before they do, but that would introduce some odd dependencies at this point. Am just asking if there's some priority mechanism that a particular contract impl class can use.
