    frontend: adjust CounterStat.name length
    
    We could just raise the limit from 127 to 400 because `Copr.name` can be
    100, `User.name` can be 100, and chroot name can be 150, plus some
    fluff that we add to the `counter_stat.name`. But `CoprDir.name` is
    unlimited, so there might be problems. I'd rather use unlimited length
    for `counter_stat.name`.
