Connect to Kafka from your code

When connecting to Kafka, you will need to use all broker endpoints injected. The environment variable, KAFKA_BROKERS, contains a comma-delimited list of endpoints (i.e. <subdomain>:<port>). Depending on the language/framework you're using, you may need to convert those into an array that is used for Kafka connection configuration.
