Add initial list of YAML files that formalize Kafka API:
- requests list that CGW can handle
- responses that CGW will generate
- unsolicited events that CGW might generate
Also a small cleanup of requests and responses was made,
to align it with a common format (renamed some of the fields,
added missing etc).
Tests are tweaked to accomodate for changed field names.
