👍 LGTM 🚀

I trust that you copy/pasted the files correctly. 😄

Do we need to anything in the docs related to PubSub and Kafka? If this needs to be done, I'm OK if you wanna create a Jira and do it in a separate PR.

It is a part of the GUIDE.md of the go-chassis and updated in a corresponding PR. Let me know if you think we need to expand the README file of the go-sdk, I will create a corresponding ticket for that 👍
