[MNG-7046] Revert MNG-5639 and make repo config static only (no ${param} interpolation)

**[Michael Osipov](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=michael-o)** opened **[MNG-7046](https://issues.apache.org/jira/browse/MNG-7046?redirect=false)** and commented

As discussed in MNG-5639 repositories should always be known upfront, they have to be static to avoid chicken and egg situations, a project should not influence settings. It should be the way around.

In subsequent ticket it will be verified that repo configuration does not contain any expression: https://github.com/apache/maven/commit/d411c3fa98832e7d86d901fe86ff63ba907cf868#commitcomment-44782281.
