Implement adaptive backoff for compaction/repairs
-------------------------------------------------

                 Key: CASSANDRA-1222
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-1222
             Project: Cassandra
          Issue Type: New Feature
            Reporter: Edward Capriolo


When nodes are in repair/streaming/compact they tend use all available IO and hurt the performance
of read requests. In our use case we do not compact very long and we always want reads to
have a priority. Our suggestion throttle compaction based on the row-read-stage.pending count.
