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.

* 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.

* [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

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

* fix yamllint

* remove addext argument

* Configure API server with the CA bundle

* add check kdd
