> Introducing an optional parameter 'concurrent_factor' into LoadTestTool. When 
> it's specified with positive integer n, LoadTestTool will load n tables 
> parallely. -tn parameter value becomes table name prefix. Tables are created 
> with name in format <tn>_1...<tn>_n. A sample command line "-tn test 
> -concurrent_factor 2" will create & load tables:"test_1" and "test_2"
> The motivation is to add a handy way to load multiple tables concurrently. In 
> addition, we could use this option to test resource leakage of long running 
> clients.
