* Update ansible-lint to 5.4.0 (#8607)

It seems that the Rich version 11.0.0 has a breaking change.
So need to update ansible-lint to 5.3.2 or later.

* Fix for ansible-lint no-changed-when rule (#8607)

[containerd] Upgrade containerd to 1.6.0 and re-enable arm64 architecture with default options (#8555)

* [containerd] add checksums for 1.6.0

* [containerd] promote 1.6.0 as the new default

* [runc] promote 1.1.0 as the new default to allow arm deployments out of the box

* [nerdctl] bump to 0.17.0 to align with containerd 1.6.0

* [reset] allow crictl stopp and rmp commands to fail

* [nerdctl] upgrade nerdctl to 0.16.0

* [nerdctl] add configuration file

* Use sysctl_file_path variable for all sysctl_file locations

* Add sysctl_file_path variable to kubespay-defaults

* Remove previously used sysctl file locations if present

* Use explicit filename in roles/kubernetes/node/defaults/main.yml

* Defaults: use explicit value

* fix reset containerd_storage_dir

* add env to kubespray-defaults

* Reset: Fedora uses NetworkManager

* CI: test reset on fedora

* Kata-containes: Fix for ubuntu and centos sometimes kata containers fail to start because of access errors to /dev/vhost-vsock and /dev/vhost-net

* Kata-containers: use similar testing strategy as gvisor

* Kata-Containers: adjust values for 2.2.0 defaults

Make CI tests actually pass

* Kata-Containers: bump to 2.2.2 to fix sandbox_cgroup_only issue

restarting network in ubuntu 21.04 fails and checked the restart menu and found that hirsute was missing in the argument : )

* Containerd: download containerd from upstream instead of using distro specific packages

split runc download to separate role
make bootstrap-os role deploy container-selinux and seccomp libraries
clean up package manager provided containerd
move variables to docker role that are no longer common with containerd

* Containerd: make molecule testing more relevant

* replace ubuntu18 with ubuntu20
* add centos8 and debian11 to molecule tests
* run kubernetes/preinstall role to ensure relevancy
  of test including dependency packages

* CI: adjust test scenarios for downloaded containerd

If the etcd cluster is separate and the etcd_deployment_type is "host",
there is no need for a container engine on the etcd nodes

Do not rely on a 'default(true)' filter, but define a proper default in
kubespray-defaults depending on etcd deployment method and if internal
or external etcd is used

* Ansible: move to Ansible 3.4.0 which uses ansible-base 2.10.10

* Docs: add a note about ansible upgrade post 2.9.x

* CI: ensure ansible is removed before ansible 3.x is installed to avoid pip failures

* Ansible: use newer ansible-lint

* Fix ansible-lint 5.0.11 found issues

* syntax issues
* risky-file-permissions
* var-naming
* role-name
* molecule tests

* Mitogen: use 0.3.0rc1 which adds support for ansible 2.10+

* Pin ansible-base to 2.10.11 to get package fix on RHEL8

When reset, need to clean up directory /usr/libexec.

When reset, need to clean up files kube_proxy-ipvs.conf and kubespray-br_netfilter.conf.

* Clean up residual files

When reset, you need to clean up to the kerw directory.

* Update main.yml

* Add krew support

* Add reset for krew

* Update install krew(local)

* ansible lint

* yamllint

* fix krew default vars

* fix kubectl_localhost mode

* replace include

* fix e206

* rename ansible groups to use _ instead of -

k8s-cluster -> k8s_cluster
k8s-node -> k8s_node
calico-rr -> calico_rr
no-floating -> no_floating

Note: kube-node,k8s-cluster groups in upgrade CI
      need clean-up after v2.16 is tagged

* ensure old groups are mapped to the new ones

* Add nerdctl cli tool for containerd user

* Add nerdctl enable option

* Add nerdctl enable option and update nerdctl version to 0.8.0

While at it remove force_certificate_regeneration
This boolean only forced the renewal of the apiserver certs
Either manually use k8s-certs-renew.sh or set auto_renew_certificates

On CentOS 8 they seem to be ignored by default, but better be extra safe
This also make it easy to exclude other network plugin interfaces

By default Ansible stat module compute checksum, list extended attributes and find mime type

Running remove-node.yml tasks for clean up cluster on Fedora CoreOS.
The task failed to restart network daemon (task name: "reset | Restart network").
Fedora CoreOS is essentially using NetworkManager, but this task returns network.

If crictl (and docker) binaries are deployed to the directories
that are not in standard PATH (e.g. /usr/local/bin), it is required
to specify full path to the binaries.

crio refuses to delete pods when cni is unavailable which is the
case e.g. using calico with kdd datastore. See:

https://github.com/cri-o/cri-o/issues/4084

Fix by deleting storage associated with containers. Stop and disable
crio service so switching container runtime can be done.
