non-kubeadm mode has been removed since ddffdb63
2.5 years ago. The non-kubeadm makes unnecessary confusion today, then
this updates the documentation.

- Added a hint about the kube_proxy_strict_arp configuration, which is required for MetalLB to work
 - See also https://github.com/kubernetes-sigs/kubespray/pull/5180/files

Previously IDs of container images were gotten from tar files of container
images but that way was wrong. If multiple json files are contained in a
tar file, the script got multiple IDs and tried to pass these IDs on
`docker tag` command. Then the command was failed.

This updates the script to get image IDs from `docker image inspect` command
to fix this issue.
In addition, this adds a check a registry container exists already or not
before deploying registry container to avoid a container conflict failure.

* 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The one provided in Debian 10 repositories is outdated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

* fix(misc): terraform/aws

- handles deployment with a single availability zone
- handles deployment with more than two availability zone
- handles etcd collocation with control-plane nodes (`aws_etcd_num=0`)
- allows to set a bastion instances count (`aws_bastion_num`)
- allows to set bastion/etcd/control-plane/workers rootfs volume size
- removes variables from terraform.tfvars that were not re-used
- adds .terraform.lock.hcl to .gitignore
- changes/updates base image from ubuntu-18.03 to debian-10

tested by a few coworkers of mine, and myself: thanks for the outstanding
work, on both those terraform samples and kubespray playbooks.
I did not test ubuntu deployments, I could still swap from buster to
focal. LMK.

* fix(gitlab-ci)

AFAIU, terraform.tfvars indentation should be fixed for / no diff
returned running `terraform fmt -check -diff`

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.

tf-elax_ubuntu18-calico is so flake today. The test job is failed
due to SSH connectivity check error after deploying virtual machines
which are used for Kubernetes nodes.
This allows failure on the job to see the test situation without
pull request merger failures.

When running the script, I faced the following error but it was
difficult to know the root problem due to lack of error handling.

  docker tag" requires exactly 2 arguments.
  See 'docker tag --help'.

  Usage:  docker tag SOURCE_IMAGE[:TAG] TARGET_IMAGE[:TAG]

  Create a tag TARGET_IMAGE that refers to SOURCE_IMAGE

To investigate such errors easily, this adds an error handling.

* csi-driver: Added possibility to use application credentials for cinder

* external-cloud-controller: Added env vars for openstack application credentials

* set selinux type t_etc if selinux state is enforcing

* workaround with update repo is no longer needed
remove comments about failing playbook

* grubby is not available in distros using ostree

* remove docker support because removed in fcos
update install script example with live rootfs

* do not call grubby on ostree based distro

* update docs enabling containerd on fedora coreos

Update README for control_plane's external volume type variable

Clean up extra spaces, although these errors are not important, they affect the code specification.
