Initial infrastructure for dealing with Kafka protocol in Go

[grcevski]

This PR doesn't add any visible functionality, it adds support for Kafka tracking in Go, but we ignore the events. I'm adding the PR so that @marctc can build the remaining protocol parsing, which is common for non-Go.

I added components for integration testing in Go, but I can't write any tests yet since we don't parse the protol info.

Relates to #872
