Config: Reduce delete probability to 25%
Now that all of the most high-traffic end points have been migrated, we
should start taking advantage of Cassandra's range deletes in a more
efficient manner. Hence, reduce the delete probability from 100% on each
request to 25%. This should alleviate some of the load on the Cassandra
3 cluster.
