aufs-tools was required for docker.io package originally,
but Kubespray installs docker-ce package instead today.
In addition, Ubuntu 20.04 doesn't provide aufs-tools as [1].
Then this removes aufs-tools from Ubuntu requirement.

* [CI] ensure packet job tests metal

Since https://github.com/kubernetes-sigs/kubespray/pull/8434

* kata container related options exist in k8s-cluster.yml,
  not k8s_cluster.yml

* https://github.com/kata-containers/runtime has been archived and
  https://github.com/kata-containers/kata-containers is used today.

For offline mode

* As per this issue https://github.com/kubernetes-sigs/kubespray/pull/8664 I propose to make etcd v.3.5.3 default for any kubernetes version which uses 3.5.x since that 3.5.[0-2] not recommended for production.

Add tag to AWS VPC subnets for automatic subnet discovery by load balancers or ingress controllers (#8705)

* [upcloud] add upcloud csi-driver

* Option to use ansible_host as api ip for kubueconfig

* - add ability to specify the network_zone in hetzner terraform
- Export the network id from hetzner terraform the the generated inventory.ini

* - Add with_networks variable to allow different deployments of hcloud controller manager

- Add network id to hcloud controller secret (added via the inventory)

- Don't include extra_args if it's not set

Current ansible.tags 'facts' is for skipping actual Kubespray deployment
at vagrant CI because the deployment takes much time. However the static
'facts' skips the deployment for normal usage of vagrant also.
That causes confusions.

This adds VAGRANT_ANSIBLE_TAGS to skip the deployment for vagrant CI.

The quotations in the variable nerdctl_extra_flags are not required for the `nerdctl_image_pull_command` and throw the following error when executing the cluster-playbook with `container_insecure_registries` set:
        unknown flag: --insecure-registry\\\"
This happens as the complete nerdctl_image_pull_command string variable gets split into an array string for the cmd task. The escaped quotation doesn't get escaped properly and is added to the cmd-string array as part of the command. This leads to a wrong written insecure-registry flag, which throws this error.

* [calico] add calico apiserver
