Since it is unsupported to skip upgrades, I've detailed the steps for upgrading a step at a time and removed some language that indicated it should work

Secrets and ConfigMap should be created before dashboard pod run.

When using cluster.yml or scale.yml to add/scale nodes in the existing
k8s cluster, the `kubeadm init` wouldn't run. As a result, kube-proxy
wouldn't be created, and therefore the kube-proxy deletion task would
fail, e.g. in the case where kube-router is used and "kube_proxy_remove"
is set to true. As a workaround, add ignore_errors to the kube-proxy
deletion task.

It's unnecessary and breaks when running from within a docker container:
```
An exception occurred during task execution. To see the full traceback, use -vvv. The error was: TimeoutError: Timer expired after 10 seconds
fatal: [localhost]: FAILED! => {"changed": false, "cmd": "/usr/sbin/udevadm info --query property --name /dev/mapper/vg00-root", "msg": "Timer expired after 10 seconds", "rc": 257}
```

The script is not usable unless you are in the '.vagrant/provisioners/ansible/inventory/artifacts' folder.
This update makes this usable from anywhere.

- do not run etcd role when etcd_kubeadm_enabled == true
- remove default value 'systemd' for cgroup driver in containerd role.
  this value override autodetect in kubelet_cgroup_driver_detected from docker info

This allows to easily override the gcr, quay, and docker repos with the
mirror repos in countries like China, where the default accesses are
blocked or unstable.
