> we need a nodetool command that outputs columnfamilystore RecentReadLatencyHistogramMicros,
RecentReadLatencyHistogramMicros, and (for 0.7) getRecentReadLatencyHistogramMicros.
> i'd like this to be in a vertical display with the histogram bucket values from EstimatedHistogram
displayed.  Like this:
> {code}
> 1               0
> 15              1        
> 18            542
