* 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.

During the reset, restart network was not completing in distros
like RHEL/CentOS/AlmaLinux with major version higher than 8.
Example:
kubespray> ansible-playbook -i inventory/mydomain/hosts.yml reset.yml -b -v
fatal: [mynode]: FAILED! => {"changed": false, "msg": "Could not find the requested service network: host"}

by setting a default runtime spec with a patch for RLIMIT_NOFILE.
- Introduces containerd_base_runtime_spec_rlimit_nofile.
- Generates base_runtime_spec on-the-fly, to use the containerd version
of the node.
- Update and re-work the documentation:
- Update links
- Fix formatting (especially for lists)
- Remove documentation about `useAlphaApi`,
a flag only for k8s versions < v1.10
- Attempt to clarify the doc
- Update to version 1.5.0
- Remove PodSecurityPolicy (deprecated in k8s v1.21+)
- Update ClusterRole following upstream
(cf https://github.com/kubernetes-sigs/sig-storage-local-static-provisioner/pull/292)
- Add nodeSelector to DaemonSet (following upstream)
