This allows us to use util methods from within config, which is a useful thing to be able to do for, e.g., being able to log errors while loading configuration. It makes sense that the util package should be at the very base of the class inheritance hierarchy; config seems logically higher than it. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=144324273
