> HBASE-4440 adds a 'presplit' option to PerformanceEvaluation utility.
> when the splits are generated, the first split has row-end-key=0 (zero).  Hence this
split doesn't get any data.
> For example, 
> if total keyspace is 100, and splits requested are 5, 
> generated splits => [0, 20, 40, 60, 80]
> it should be => [20, 40, 60, 80, 100]
