Allow certain configured groups to by-pass the PR-only setting
    
    Pagure has a setting that can be set for each project to disallow
    direct commit and instead have all contribution be made via
    pull-requests.
    On dist-git (src.fp.o), if enabled, this feature has the unforseen
    consequences of blocking provenpackager or releng from fixing
    packages directly and forcing them into this PR-only model.
    This is not ideal as we want provenpackager or releng to be able to
    fix quickly packages that need to be.
