proxies: redirect old packages to new
    
    The old packages app (which was before that the old community app) lived
    on https://apps.fedoraproject.org/packages/ It hasn't been active there
    since the datacenter move last year (we retired it). A new openshift app
    has been created that lives on https://packages.fedoraproject.org now.
    We want to redirect the old path to the new one and remove the old
    reverseproxy to nowhere.
    
    Fixes infra ticket #10212
