Subject Re: Pruning commit logs manually

Don't manually remove commit logs.

Retention of commit logs should hopefully be because there are column
familities that don't flush because they don't reach their thresholds
in a long time. Decrease the expiry time for memtable flushing to make
them flush more often.

Flushing is relevant because only when a memtable is flushed can the
commit log which contains the data being flushed, be removed by
