> kafka-consumer-perf-test is a great tool to quickly check raw consumer 
> performance. Currently, It subscribes to all the partitions and gives overall 
> cluster performance, however If we want to test performance of single 
> broker/partition, existing tool does not support.
> We can introduce two optional flags --partitions and --offsets which gives 
> flexibility to benchmark only specific partitions optionally from specified 
> offsets.
