Add Cruise Control

LinkedIn has open-sourced several of the tools they use to manage their Kafka clusters. Adding them into the stack would make it easy to try out these tools and get a feel for how they work.

Note that this probably isn't too valuable in this stack as-is today, as the stack only has a single broker.

This may be more valuable if (when?) the stack is expanded to include multiple brokers... or more interestingly, another version of the stack could be built out with additional brokers? 😀
