Description

Introducing an optional parameter 'num_tables' 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 -num_tables 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.
