- kubeadm: increased the verbosity of API client dry-run actions during the subcommands "init", "join", "upgrade" and "reset". It also allowed dry-run on 'kubeadm join' even if there was no existing cluster by utilizing a faked, in-memory cluster-info ConfigMap.

// concDo calls actions concurrently. selfActionFn is run for the current

- Cloud controller manager's node controller now emits timing metrics for initial `Node` synchronization. These metrics measure the delay between the creation of a new `Node` and the node controller's initial management actions, such as removing the cloud provider taint. These metrics should be consulted when setting cloud controller manager's `--concurrent-node-syncs` flag.

- 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`
  package for one more release, but in you must adapt your scripts to install `crictl` manually from
