Explicitly expose ongoing per-node tasks (like compactions, repair, etc) and est. % done
----------------------------------------------------------------------------------------

                 Key: CASSANDRA-1516
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-1516
             Project: Cassandra
          Issue Type: Wish
          Components: Core
            Reporter: paul cannon
            Priority: Minor


so major compaction, read-only compaction, repair, drain, and bootstrap are the on-node tasks
I'm pretty sure make sense to be exposed in this way.  snapshotting might make sense too.

some of these can be "detected" using heuristics on the number of tasks alive in different
stages, but it would be preferable if it could be made more clear.

the interface should allow multiple tasks and respective percentages to be ongoing at the
same time, especially since some tasks (like repair) implicitly kick off other sub-tasks (compaction)
and both of them would normally show up at the same time.
