- Kubeadm: fix a bug where file copy(backup) could not be executed correctly on Windows platform during upgrade ([#117861](https://github.com/kubernetes/kubernetes/pull/117861), [@SataQiu](https://github.com/SataQiu)) [SIG Cluster Lifecycle]

- `kubeadm`: fixed a bug where file copy(backup) could not be executed correctly
  on Windows platform during upgrade. ([#117861](https://github.com/kubernetes/kubernetes/pull/117861), [@SataQiu](https://github.com/SataQiu))
- `kubeadm`: speedup init by 0s or 20s. kubelet-start phase is now after etcd

    * While this is a backwards-incompatible change, it would have been impossible to setup reliable monitoring around these metrics since the labels were not stable. 
* Fix keymutex issues which may crash in some platforms. ([#74386](https://github.com/kubernetes/kubernetes/pull/74386), [@danielqsj](https://github.com/danielqsj))

  amd64 binary instead of the go-runner that matches that architecture.
  
  This commit explicitly sets the '--platform=linux/${arch}' to ensure
  we're pulling the correct go-runner arch from the manifest list.
