public static @interface ProductionSubcomponent.Builder
This follows all the rules of Component.Builder, except it must appear in classes
annotated with ProductionSubcomponent instead of Component.
If a subcomponent defines a builder, its parent component(s) will have a binding for that
builder type, allowing an instance or Provider of that builder to be injected or
returned from a method on that component like any other binding.
