Proposed fix to Issue 8667

Proposed fix to Issue 8667

When running molecule jobs, we saw the folloing warning message:

 [DEPRECATION WARNING]: [defaults]callback_whitelist option, normalizing names
 to new standard, use callbacks_enabled instead. This feature will be removed
 from ansible-core in version 2.15. Deprecation warnings can be disabled by
 setting deprecation_warnings=False in ansible.cfg.

callbacks_enabled has been added since Ansible 2.11 and Kubespray is using
Ansible 2.12 at master branch. So we can use callbacks_enabled safely to
avoid the warning message.

Ansible v2.9 and v2.10 are EOL as [1].
This drops those version supports by following the upstream Ansible.

This sets use_ssh_args true always because that is required to use
ssh_args on ansible.cfg on Ansible v2.11 or later[2].

ansible_ssh_host is replaced with ansible_host because ansible_ssh_host
has been deprecated already and cenots7 jobs were failed due to the
deprecated ansible_ssh_host.

* Allow disabling calico CNI logs with calico_cni_log_file_path

Calico CNI logs up to 1G if it log a lot with current default settings:
log_file_max_size	100	Max file size in MB log files can reach before they are rotated.
log_file_max_age	30	Max age in days that old log files will be kept on the host before they are removed.
log_file_max_count	10	Max number of rotated log files allowed on the host before they are cleaned up.

See https://projectcalico.docs.tigera.io/reference/cni-plugin/configuration#logging



To save disk space, make the path configurable and allow disabling this log by setting
`calico_cni_log_file_path: false`

* Fix markdown

* Update roles/network_plugin/canal/templates/cni-canal.conflist.j2

If opening https://groups.google.com/g/kubernetes-dev we can see the
following message:

  As of January 2, 2022, this group will be sunset in favor of dev@kubernetes.io.

So this replaces kubernetes-dev@googlegroups.com with the new one.

In addition, this adds actual steps to know how to create container images easily.
