At the upstream calico development, the v3.21 branch is not updated
over 2 monthes. In addition, unnecessary error message is output at
Kubespray deployment due to different URLs for calico v3.21 or v3.22+
This drops the v3.21 support to solve the issue.
Without minimal cluster configuration, even on a one node control plane,
the health check of the ovn-cental container always fails as it queries the
cluster/status.
Crio registries configuration changed from crio_registries_mirrors to
crio_registries. The configuration in the test was however forgotten.

* feat(): Add wireguard backend to flannel cni
As described in the flannel docs:
https://github.com/flannel-io/flannel/blob/master/Documentation/backends.md#wireguard
This does not support optional configuration methods like:
- setting a psk (will be autogenerated by default)
- chang listening ports
- change mode (defaults to 'separate')
- change PersistentKeepaliveInterval (defaults to 0)
* Add supported backends to flannel docs
* Fix markdown in docs
This fixes a task failure in the rescue block that uncordons nodes after an unsuccessful drain. The issue occurs when `kube_override_hostname` is set and does not match `inventory_hostname`.
The `containerd-common` role is responsible for gathering OS specific variables from the vars directory of the roles that include or import it. `containerd-common` is imported via role dependency by a total of two roles, `container-engine/docker`, and `container-engine/containerd`.
containerd-common is needed by both the docker and containerd roles as a dependency when:
- containerd is selected as the container engine
- a docker install is detected and needs to be removed
- apt is the package manager
However, by default, roles can not be invoked more than once in the same play, unless `allow_duplicates: true` is set for that role. This results in the failure of the `containerd | Remove containerd repository` task, since only the docker vars will be loaded in the play, and `containerd_repo_info.repos`, normally populated by containerd/vars, is left empty.
This change sets `allow_duplicates: true` for `containerd-common` which fixes the currently failing containerd tasks if docker was detected and removed in the same play.
