* AlmaLinux: ansible>2.9.19 is needed to know about AlmaLinux

* AlmaLinux: identify as a centos derrivative

* AlmaLinux: add AlmaLinux to checks for CentOS

* Use ansible_os_family to compare family and not distribution

As the official document[1], the parameter keepcache should be
'0' or '1' as string. To avoid the following warning message,
this fixes the parameter value:

  [WARNING]: The value False (type bool) in a string field was
  converted to u'False' (type string). If this does not look
  like what you expect, quote the entire value to ensure it
  does not change.

This replaces kube-master with kube_control_plane because of [1]:

  The Kubernetes project is moving away from wording that is
  considered offensive. A new working group WG Naming was created
  to track this work, and the word "master" was declared as offensive.
  A proposal was formalized for replacing the word "master" with
  "control plane". This means it should be removed from source code,
  documentation, and user-facing configuration from Kubernetes and
  its sub-projects.

NOTE: The reason why this changes it to kube_control_plane not
      kube-control-plane is for valid group names on ansible.

* Add crun download_url and checksum

* Added experimental cri-o support for Amazon Linux 2

* Fixed dependencies order

When privileged is enabled for a container, all the `/dev/*` block
devices from the host are mounted into the guest. The
`privileged_without_host_devices` flag prevents host devices from
being passed to privileged containers.

Ubuntu 18.04 crio package ships with 'mountopt = "nodev,metacopy=on"'
even if GA kernel is 4.15 (HWE Kernel can be more recent)

Fedora package ships without metacopy=on

By default Ansible stat module compute checksum, list extended attributes and find mime type
To find all stat invocations that really use one of those:
git grep -F stat. | grep -vE 'stat.(islnk|exists|lnk_source|writeable)'

`containerd.io` is the companion package of `docker-ce` and is the
proper package name. This is needed to avoid apt upgrade/dist-upgrade
from breaking kubernetes.

This makes the docker role work the same as the containerd role.
Being able to override this is needed when you have your own debian
repository. E.g. when performing an airgapped installation

This was introduced in 143e2272
Extra repo is enabled by default in CentOS, and is not the right repo for EL8
Instead of adding a CentOS repo to RHEL, enable the needed RHEL repos with rhsm_repository

For RHEL 7, we need the "extras" repo for container-selinux
For RHEL 8, we need the "appstream" repo for container-selinux, ipvsadm and socat

Here the desciption from Ansible docs
Corresponds to the --force-yes to apt-get and implies allow_unauthenticated: yes
This option will disable checking both the packages' signatures and the certificates of the web servers they are downloaded from.
This option *is not* the equivalent of passing the -f flag to apt-get on the command line
**This is a destructive operation with the potential to destroy your system, and it should almost never be used.** Please also see man apt-get for more information.
