Merge "Adding the CompactionManagerMBean" from Amnon
"This series adds the CompactionManagerMBean its implementation and its associated metrics the CompactionMetrics. The implementation is based on the api that defined in compaction_manager.json. After the series it will be possible to connect with jconsole and observe the CompactionManager and CompactionMetrics"
