  1. Cassandra: disable two particularly slow metrics

    Disabling these two metrics speeds up the scrape time dramatically on our Cassandra cluster - from around 20 seconds to 3 seconds.
    
    I think it's worth disabling these by default because it makes the JMX exporter much more usable with Cassandra and this trick isn't particularly obvious.
