[#8] Duplicate logic for parsing of Kafka headers

See original GitHub issue

I found that the classes RecordUtil and KafkaMessageHelper implement the same use case: getting and decoding Kafka headers. It would be good to have this implemented only once.

Well, taking the first header and not causing an error is still not my preference, but at least there’s some consistency to it. So, ok. Interestingly, the Kafka Headers interface only has a lastHeader method for getting a single header.

@b-abel @calohmn We already deal with handling of multiple headers having the same key in Hono. In case of HTTP headers, we take the first header value. We could apply the same here in case of kafka headers too and keep it uniform. IMHO what is important, is to clearly document the behavior in the specifications.

EDIT: In case of MQTT property bag, if there are more than one values for the specified name, then the first value is used.
