[tor-commits] [metrics-web/master] Remove functionality to look up all descriptors of a consensus.

commit b906c881998a1682d3c4e13c61fbb23e78754018

    Remove functionality to look up all descriptors of a consensus.
    
    Due to Apache's logs, this functionality was last used in November 2011.
    Could be a useful feature, but nothing that should prevent us from
    removing details from the metrics database.
