Changes for Kafka installation added

I'd like to find a clean way to specify these URL's. In a hardware deployment our bootstrap IP is not `10.0.100.3`. We have the library function `[get_binary_server_url](https://github.com/bloomberg/chef-bcpc/blob/hadoop_hortonworks/cookbooks/bcpc-hadoop/libraries/utils.rb#L129-L132)` to automate finding the proper URL -- however, how best to use that is escaping me at the moment.
