perf bench: Add --repeat option
There are a number of benchmarks that do single runs and as a result does not really help users gain a general idea of how the workload performs. So the user must either manually do multiple runs or just use single bogus results. This option will enable users to specify the amount of runs (arbitrarily defaulted to 10, to use the existing benchmarks default) through the '--repeat' option. Add it to perf-bench instead of implementing it always in each specific benchmark.
