If running Kubespray on static IP environments, a task was failed like:

fatal: [ak8s2]: FAILED! => {

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.
[1]: https://github.com/kubernetes/enhancements/blob/master/keps/sig-cluster-lifecycle/kubeadm/2067-rename-master-label-taint/README.md#motivation
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

In some environments, it might not be possible to ping the IP address
of the nodes, e.g., because ICMP echo is blocked.
This commit allows kubespray to be configured to disable the ping
check, while performing all other checks.
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.
The task outputs the following warning:
TASK [kubernetes/preinstall : Enable ip forwarding]
[WARNING]: The value 1 (type int) in a string field was converted
to u'1' (type string). If this does not look like what you expect,
quote the entire value to ensure it does not change.

When stopping at the check of "Stop if ip var does not match local ips"
the error message is like:
fatal: [single-k8s]: FAILED! => {
"assertion": "ip in ansible_all_ipv4_addresses",
"changed": false,
"evaluated_to": false,
"msg": "Assertion failed"
}
That doesn't contain actual IP addresses and it is difficult to understand
what was wrong. This adds the error message which contain actual IP addresses
to investigate the issue if happens.
* calico: add constant calico_min_version_required

The variable is defined in `kubernetes/preinstall` role and used in several roles. Since `kubernetes/preinstall` is not always included when `ansible-playbook` is run with tag selectors (see #5734 for reason), they will fail, or individual roles must copy the same fact definitions (as in #3846). Moving the definition to the always-included `kubespray-defaults` role will resolve the dependency problem.
- This solves issue #5721 & #5713 (dupes)
- Provide a cleaner default usage pattern for the download role
around etcd that supports 'host' and 'docker' properly
- Extract the 'etcdctl' as a separate task install piece and reuse it where
appropriate
- Update the kubeadm-etcd task to reflect the above change
