Explicitly expose ongoing per-node compaction tasks and est. % done
-------------------------------------------------------------------

                 Key: CASSANDRA-1586
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-1586
             Project: Cassandra
          Issue Type: Wish
          Components: Core
            Reporter: paul cannon
            Priority: Minor


CompactionManagerMBean exports the number of bytes compacted and the total number to be compacted
during a given job, but I don't believe it says what sort of compaction it's doing (anti-compaction,
validation compaction, index build, or an SSTable build after receiving an incoming streamed
file).

Is it possible to have multiple threads going in the compaction manager?  (It doesn't look
like it, but I don't see any explicit maximumPoolSize setting.)  If so, cassandra should also
expose all ongoing compaction tasks and progress for each individually.
