- Kubeadm: fixed a bug during kubeadm upgrade, where it is not possible to mount a new device and create a symbolic link for /etc/kubernetes...

  - Fix an error where existing nodes were not considered as destinations while finding place for pods in scale-down simulations
  - Remove redundant log lines and reduce severity around parsing kubeEnv
  - Don't treat nodes created by virtual kubelet as nodes from non-autoscaled node groups
  - Remove redundant logging around calculating node utilization
  - Add configurable `--network` and `--rm` flags for docker in `Makefile`

- Introduced new metrics removing the redundant subsystem in kube-apiserver pod logs metrics and deprecate the original ones:
