    Upgrade process should not crash on named restart
    
    When either dirsrv or krb5kdc is down, named service restart in
    ipa-upgradeconfig will fail and cause a crash of the whole upgrade
    process.
    
    Rather only report a failure to restart the service and continue
    with the upgrade as it does not need the named service running. Do
    the same precaution for pki-ca service restart.
