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.

* contrib/terraform/exoscale: Rework SSH public keys

Exoscale has a few limitations with `exoscale_ssh_keypair` resources.
Creating several clusters with these scripts may lead to an error like:

```
Error: API error ParamError 431 (InvalidParameterValueException 4350): The key pair "lj-sc-ssh-key" already has this fingerprint
```

This patch reworks handling of SSH public keys. Specifically, we rely on
the more cloud-agnostic way of configuring SSH public keys via
`cloud-init`.

* contrib/terraform/exoscale: terraform fmt

* contrib/terraform/exoscale: Add terraform validate

* contrib/terraform/exoscale: Inline public SSH keys

The Terraform scripts need to install some SSH key, so that Kubespray
(i.e., the "Ansible part") can take over. Initially, we pointed the
Terraform scripts to `~/.ssh/id_rsa.pub`. This proved to be suboptimal:
Operators sharing responbility for a cluster risk unnecessarily replacing resources.

Therefore, it has been determined that it's best to inline the public
SSH keys. The chosen variable `ssh_public_keys` provides some uniformity
with `contrib/azurerm`.

* Fix Terraform Exoscale test

* Fix Terraform 0.14 test

* Fix calico-rr tasks

* revert stdin only when it's already a string

* update local-path-storage config template to version v0.0.19

* changes local_path_provisioner image tag to v0.0.19

* removes copy paste example from rancher local-path-provisioner repo

According to the following recommendation, this moves the directory
to control-plane:

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 is a small step to replace "master" with "control-plane" in
Kubespray project.

Fixes the following error when using Bastion Node with the sample config.

```

Add retries to drain during upgrade. Allow leaving nodes cordoned after drain failure. Allow continuing upgrade if drain fails. (#7206)

* Allow configureable vni and port for flannel overlay

* additional options for azure cloud config

Previous check for presence of NM assumed "systemctl show
NetworkManager" would exit with a nonzero status code, which seems not
the case anymore with recent Flatcar Container Linux.

This new check also checks the activeness of network manager, as
`is-active` implies presence.

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
