    fastestmirror: move the logic before MD retrieval. BZ 1428210
    
    This plugin has had no effect on metadata downloads since commit a522869
    in yum where we put a RepoStorage.retrieveAllMD() call before
    postreposetup_hook used by this plugin.  Let's change to using
    prereposetup_hook instead so that retrieveAllMD() can make use of the
    sorted urls.
    
    In practice, though, mirrors would still be benchmarked and sorted
    because of a similar mechanism present in urlgrabber (the timedhosts
    option, always enabled in yum) with one exception:  If the yum cache is
    empty (no timedhosts file yet), the original order received from the
    server would be retained (a property of stable sorting [1]) for the
    repomd.xml download, which is still a bad situation that wouldn't happen
    before a522869; this is fixed with this commit as it allows the plugin
    to do its work beforehand.
    
    Note that the stuff we do in yum/repos.py in between prereposetup_hook
    and postreposetup_hook has nothing to do with our plugin anyway, so we
    won't "miss" or break any configuration steps when we move our logic
    from the latter to the former location.
