Add setRepositories() to ModelRequest, just like ArtifactDescriptorRequest has

[vorburger]

For the sort of use which https://github.com/enola-dev/enola/pull/1065/files outlines, where I have a Mima class to further simplify for how MIMA already simplifies 😆 the Maven Resolver, I would have found it useful to (a) be able to specify the default list of Maven repos (I anticipate this probably going to be some some CLI option of my tool, in the future), BUT then (b) for individual Artifact resolutions also wanting to still be able to override that, for "I want the group:artifact:version specfically from that repo, only".

I would use this in the context of enola-dev/enola#1066, for an URI such as pkg:maven/org.apache.xmlgraphics/batik-anim@1.9.1?repository_url=repo.spring.io/release (an example found here).

ModelRequest currently does not have a setRepositories() such as ArtifactDescriptorRequest does.

The way I would implement this would be to give it "predence", if it's set, here.

@cstamas Would you be open to review if a raise a PR proposing to add this? Or would you rather not have such an API?

[cstamas]

Sure!

[vorburger]

Sure!

Cool. I've raised #167.

BTW Once reviewed & merged, I don't suppose you would consider to release just with that? Then I would wait until you create a new release later. I don't suppose you would like to keep an open issue for the next release, which I could subscribe to, to watch out for it?
