This replaces KUBE_MASTERS with KUBE_CONTROL_HOSTS 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.
```

This updates Ansible version to the latest stable version 2.9.17.

Since a790935d all proxy users
should be properly configured

Now when you have *_PROXY vars in your environment it can leads to failure
if NO_PROXY is not correct, or to persistent configuration changes
as seen with kubeadm in 1c5391dd

Instead of playing constant whack-a-bug, inject empty *_PROXY vars everywhere
at the play level, and override at the task level when needed

* Move proxy_env to kubespray-defaults/defaults

There is no reasons to use set_facts here

* Ensure kubeadm doesn't use proxy

*_proxy variables might be present in the environment (/etc/environment, bash profile, ...)
When this is the case we end up with those proxy configuration in /etc/kubernetes/manifests/kube-*.yaml manifests

We cannot unset env variables, but kubeadm is nice enough to ignore empty vars

`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.

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.

* Add unique annotation on coredns deployment and only remove existing deployment if annotation is missing.

* Ignore errors when gathering coredns deployment details to handle case where it doesn't exist yet

* Remove run_once, deletegate_to and add to when statement

* Added force_etcd_cert_refresh var to maintain existing functionality. Broke out etcd node cert syncing from member and admin cert sync logic. Now first etcd will sync node certs to other etcd members on every run to keep all etcds up to date after adding additional worker nodes to the cluster

* Updated etcd cert check tasks to better detect when new certificates need to be generated

* Move usage of force_etcd_cert_refresh var to gen_certs fact set

* Force etcd cert generation per server if force_etcd_cert_refresh is set to true

* Include gathering of node certs even if k8s-cluster member and in etcd group.

* Removed run_once due to when statement

Helm v3.5.2 is a security (patch) release. Users are strongly
recommended to update to this release. It fixes two security issues in
upstream dependencies and one security issue in the Helm codebase.

See https://github.com/helm/helm/releases/tag/v3.5.2

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

When enable_dual_stack_networks is set, we need to make sure
IPv6DualStack=true is set too, otherwise we end up with
a broken cluster.
