* [etcd] ensure etcd is properly upgraded when managed by kubeadm

* [CI] add periodic job to test upgrade of etcd managed by kubeadm

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

* fix yamllint

* remove addext argument

* [containerd] add hashes for 1.5.11

* [containerd] add hashes for 1.6.2

* [containerd] make 1.6.2 the new default

Due to missing quotation of nerdctl_extra_flags, ansible-playbook was failed:

  Using module file /usr/local/lib/python3.6/dist-packages/ansible/modules/command.py
  Pipelining is enabled.
    [..]
    File "/usr/lib/python3.8/shlex.py", line 191, in read_token
      raise ValueError("No closing quotation")

This fixes the issue.

T-Eberle investigated the issue and found the solution.
Thank you T-Eberle!

To read it easily, this puts new lines.

* [ansible] make ansible 5.x the new default version and move different versions tested to nightly jobs

* [CI] jobs were missing proper ansible cleanup

If running Kubespray on static IP environments, a task was failed like:

  TASK [kubernetes/preinstall : Configure dhclient hooks for resolv.conf (RH-only)]
  fatal: [ak8s2]: FAILED! => {
    "changed": false, "checksum": "..",
    "msg": "Destination directory /etc/dhcp/dhclient.d does not exist"}

This adds a check for dhclientconffile for running 0100-dhclient-hooks to
run the task only if dhcpclient is enabled.

terrform/openstack: Fix templating of ansible_ssh_common_args in no_floating.yml if used as TF module (#8646)

* terraform/openstack: Use path.module for ansible_bastion_template.txt

This extends on #7643 by not using path.root, but switching to path.module
to allow use of the terraform code as a module itself. This change then keeps
all calls to the template file stable even for that use-case.

* terraform/openstack: Make sed calls fail on errors

By using a single call with two replacements to use of sed will create proper exit codes
and allowing for errors to be recognized by terraform.
