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. Signed-off-by: Oleksandr Mazur <oleksandr.mazur@plvision.eu>
