This release syncs release30 with master. No patches for release30 were needed specifically.

I would like to especially thank @Conan-Kudo for his work on the cross-distro specfile for cobbler and koan as well as @rbberger who was so kind to contribute a lot regarding building the rpms in docker for CentOS with the specfile this helped a lot!
