Title: Statistics with histogram of response times

When you want to use histogram statistics in StressTestStage you have to run another StressTestStage with identical parameters and generateHistogramRange=true prior to the actual run. This stage should be ran on already warmed-up cache and shouldn't take long - all request response times are recorded in memory, therefore it could lead to OOM. For example, 1 minute should be enough.
Remember to clean the cache between these runs.
Then the actual benchmark stage has to specify useHistogramStatistics=true in order to collect the histogram statistics.
