Do not use origin-repository.jboss.org, use repository.jboss.org instead in kie-parent pom

• repository.jboss.org is a load-balancing proxy for the jboss nexus. Nowadays it should offer much faster reads than the master one and barely slower writes (and we read far more than we write).
• origin-repository.jboss.org is the actual nexus master instance, which we must not contact directly as a good citizen.

Over 2 years ago, someone added a hack to workaround temporary stability issues with repository.jboss.org that made us go directly to origin-repository.jboss.org

That was never rolled back. Replace those 2 lines to use repository.jboss.org instead and remove the comment.

Suggested actions::

• Replace those 2 lines to use repository.jboss.org instead and remove the comment
• Look for the use of origin-repository.jboss.org in all repo's and change that too.
  • the errai/uberfire/appformer parent pom might use it too
• Delete your local .m2/repository and do a full downstream build.
• Adjust any jenkins jobs (both blessed jobs and PR jobs) that have hard coded origin-repository.jboss.org somewhere
