- Kubeadm: switched kubeadm to start using the CRI client library instead of shelling out of the `crictl` binary
  for actions against a CRI endpoint. The kubeadm deb/rpm packages will continue to install the `cri-tools`

Now that the Kotlin Gradle Plugin provides <<lazy_configuration.adoc#lazy_configuration, lazy configuration>> properties, our `kotlin-dsl` plugin switched to adding required compiler arguments to the lazy properties directly.
