`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The one provided in Debian 10 repositories is outdated

* 7816: Remove useless when condition

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.
