Kafka Performance benchmarking with SBK-GEM

[kmgowda]

Describe the Issue (Bug/Feature)
Run multiple instances of SBK from multiple nodes/hosts/systems using sbk-gem command

To Reproduce

1. setup apache kafka
2. create mutiple nodes/host with a common user name and password
3. run sbk-gem with -class kafka and other reader and/or writer options

Expected behavior
the SBK should be running in multiple systems and all the performance results should be consolidated in the one system where sbk-gem is running
