Release Note

Add two new methods in CompactionLifeCycleTracker.
The notExecuted method will be called if the selectCompaction failed or space quota limitation reached.
The completed method will be called after all the requested compactions are finished. The compaction scheduling is pre Store so if you request compaction on a region it may lead to multiple compactions.
Remove the User parameter in Region.requestCompaction methods as it is useless for CP users.
Add a boolean parameter to indicate whether you want to do a major compaction. And so that the triggerMajorCompaction method is removed.
Remove the getCompactionProgress method in Store interface.
Add a UT to confirm that CompactionLifeCycleTracker works correctly, and it also shows how to use CompactionLifeCycleTracker to wait for the completion of a compaction.
