Add Package object to Product

[zschmerber]

I would like to add the Package object to the Product object and an optional object to use.
Product.Package

We have logs that contain application architecture and no way to capture it in the Product Object.

Agreed. Also, hw_device_info does not have an architecture attribute and probably should. Where metadata.product is what the event source is, other uses of Product can be different, e.g. Application Lifecycle's app attribute is of type Product and any Discovery of products event (don't think we actually have that, just devices, users, configs).
