Hi @sgalichkin Could you review the document? I am asking you to review since you are familiar with quite a bit internal SDK details including the wire protocol. Thanks.

Personally, I really missed the detailed layout of all the messages, especially the binary ones. For example, if you look at the Kafka protocol documentation, you will see a schema of all messages, including their types, order, purpose, changes from version to version, and so on. I have to reverse-engineering your Java SDK a lot to understand how to encode binary messages. Maybe when I'm done with my SDK, I'll make a pull-request with the binary message schema added. Anyway thanks a lot for your work, for the first version of the protocol documentation it is very good.

Mostly proofreading comments. In a few places, it seems like some fairly important details are hidden deep into the document, which may benefit from having them lifted out earlier. See comments for details.

I have applied commit suggestions. Will address general comments later. Thanks of reviewing @678098 and @pniedzielski
