Description

"nodetool compactionhistory" (introduced in CASSANDRA-5078) is a useful tool for Cassandra DBAs. However, the current output limits its usefulness without some additional parsing.

We should improve it in the following two areas:
1. The output should be sorted on the compacted_at column, so that the most recently finished compaction will show up last (which is what the DBAs would expect);
2. The compacted_at column should be printed in human-readable timestamp.
