`cluster_name` defaults to `dns_domain` value (see [here][1] and [here][2])
but they could have different values.

`dns_domain` should be used here instead of `cluster_name` because the DNS
resolution is configured to use `dns_domain`.

When using Calico with:

- `calico_network_backend: vxlan`,
- `calico_ipip_mode: "Never"`,
- `calico_vxlan_mode: "Always"`,

the `FelixConfiguration` object has `ipipEnabled: true`, when it should be false:

This is caused by an error in the `| bool` conversion in the install task:
when `calico_ipip_mode` is `Never`,
`{{ calico_ipip_mode != 'Never' | bool }}` evaluates to `true`:

* During pre-upgrade add a flag to always cordon

* empty

* empty

* empty

* Better default val

- Use python3-apt instead because python-apt was removed in Debian 11
- Add gnupg (fix "container-engine/containerd : ensure containerd repository public key is installed" task failed)
- Remove aufs-tools

* Fedora and RHEL use etc_t and the convention is <type_name>_t

* Docs: specify all values for preinstall_selinux_state

* CI: Add Fedora 34 with SELinux in enforcing mode

Bump calico version to 3.19.2 due to adding 3.20.0 earlier

Fix task 'Cert Manager | Wait for Webhook pods become ready' failed due to webhook pods don't exist yet by using `retries..until` trick like kubernetes-sigs/kubespray#7842

This fix should be removed in the future if the kubernetes/kubernetes#83242 is resolved.

* feat(containerd): auth support

* fix(registry-auth): rename variable

Now that 1.10 is out this is to make 1.9.9 the default. I am running
this version successfully.

Fix task 'Cert Manager | Apply ClusterIssuer manifest' failed due to service/endpoints updating delayed even though the wekhook pod status is ready.

* CRI-O: Install libseccomp2 from backports on Debian 10

libseccomp2 is a required dependency of cri-o-runc package

The one provided in Debian 10 repositories is outdated

As this condition is handled by block

To download necessary files in advance for offline deployment,
we can see all file URLs with contrib/offline/generate_list.sh
Most URLs are downloadable, but gvisor's one is not because the
URL is a part of full URLs for gvisor.
To download gvisor's files from the URLs directory, this separates
into two URLs for runsc and the shim.
