Description

The current version of sstableofflinerelevel prints the new level hierarchy. While "nodetool cfstats ..." will tell the current hierarchy it would be nice to have "sstableofflinerelevel" output the current level histograms for easy comparison of what changes will be made. Especially since sstableofflinerelevel needs to run when node isn't running and "nodetool cfstats ..." doesn't work because of that.
