publishing: publish with release.origin if defined

[dguglielmi]

If the user provided the Origin value when creating the release, it is preferable to retain this value.

@dguglielmi By default, if the repo contains a Release, then the origin field of that Release will be used. Only if there is no Release, or if publish_upstream is set to False, do we revert to origin="Pulp 3",. This is a desired fallback to legacy pulp_deb behavior under specific circumstances.

Is there any chance you have the publish_upstream_release_fields flag set to False on your repository? If yes, just set it to True and you will get the behavior you want.

I understand. I created a new repository, and publish_upstream_release_fields is set to false (which is strange—I need to check why it's not true by default). So I thought interacting here would be a good approach. You can go ahead and close this MR. Thanks for the guidance!

That is strange, the default should definitely be True, see:
