Reduce compaction targets

Browse source 
Cmpaction is overly aggressive.  It is a lot of work to compact a run of
files for just 20% reduction in disk space, when disk space for the
Journal (i.e. low IOPS disk space should be relatively inexpensive).
Require at least a 40% reduction for a compaction job.
