This task involves removing a cyclic package dependency between Util's `product` and `product.internal` packages. Removing the cyclic dependency should be accomplished by using a `ServiceLoader` to load the implementation of `ProductFactory`. As part of this task, `ProductMap` should be converted into a class called `ProductFactory`.{markdown}

This improvement and the improvement for FACES-2752 can be made at the same time.
