There was no reason to have several different modules all providing a single thing. This approach, which creates a single UtilsModule for everything in the util package, is cleaner. This also removes provisioning of Random and StringGenerator objects in RegistryConfig.ConfigModule, which don't belong there because they aren't configuration options. This also removes insecure random entirely; it was only used in a single place to generate 24 bytes a couple times per day. We can live with the lower speed if it means we don't have to worry about multiple types of Random, or possibly using an insecure random accidentally in a place that security actually does matter. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=229751915
