Usability notes

Dkron API is poorly documented and doesn't always work as in documentation. Because of that some inconsistencies may arise

Known issues

Processors order doesn't really work, so using more than one processor isn't advised. This happens because of how Go serializes JSON and how Dkron Job API works.
