[RFE] Configurable Product Registry

[clausa]

Is your feature request related to a problem? Please describe.
Be able to specify alternative to the hardcoded CarbideRegistry, to allow serving 'products' from other public or private registries.

Describe the solution you'd like
Make the CarbideRegistry configurable (https://github.com/rancherfederal/hauler/blob/main/pkg/consts/consts.go#L53) to allow serving 'products' from an (OCI) registry:

hauler store sync --products <product>=<product-version> --product-registry=mycr.domain.tld 

where, --product-registry defaults to 'rgcrprod.azurecr.us'

Using a registry to serve 'products' will allow for signing and validation, etc.

Describe alternatives you've considered
