Right now, the porta product build is pulling dependencies from an internal NPM mirror, like this: 

https://gitlab.cee.redhat.com/3scale/porta-midstream/-/blob/3scale-amp-2/distgit/containers/3scale-amp-system/Dockerfile.in#L103

We should change the product build, such that these dependencies are provided through Cachito, as opposed to directly from the mirror. 

While both work, As Far As I Remember, Cachito is also responsible for providing some kind of manifest of all application dependencies to product security, and the way our project is set up right now, our npm deps wouldn't be included...
