Looks mostly good, just some minor issues I've commented on. The biggest - beyond the test failures - is that config/https_gob_to_stdout.json and config/tester_to_https_gob.json needs to be moved. Configuration examples live in docs/examples and since these two are related, I suggest adding a new directory called docs/examples/avro/ and putting both in there instead, ideally a short README.rst explaining what they do - something short is fine, see for example docs/examples/kafka/README.rst for a short example.

Some background: Everything in config/ is the actual code responsbile for parsing and applying configuration files, not meant for storing actual configuration. Conversely, everything in docs/ is distributed when you install Skogul on a machine, and every configuration file in docs/examples/ will be automatically tested for validity (i.e.: testet if it parses, not actually run) on "make check".
