* Adding option to disable gloablly applying a proxy to etc/yum.conf

* Change made to proxy_yum_globaly basedon reviewer feedback

* fix trailing spaces in ymllint

This fixes the Containerd + EL8 case that was missed in 7d1ab337

On CentOS 8 with proxy ansible render inline `proxy` and `module_hotfixes` options.

For example:
```
proxy=http://127.0.0.1:3128module_hotfixes=True
```

But expected result:
```
proxy=http://127.0.0.1:3128


module_hotfixes=True
```

* Use existing variable for tiller service account name

* keep crb as tiller

* bump crio version to 1.19

* crio package name has changed for debian/ubuntu
* crio upgrade does not work, see #6757

* update crio info in docs

crio refuses to delete pods when cni is unavailable which is the
case e.g. using calico with kdd datastore. See:

https://github.com/cri-o/cri-o/issues/4084

Fix by deleting storage associated with containers. Stop and disable
crio service so switching container runtime can be done.

* Added option to force apiserver and respective client certificate to be regenerated without necessarily needing to bump the K8S cluster version

* Removed extra blank line

Handlers with the same name (Kubeadm | restart kubelet) leads to incorrect playbook execution. As a result, after completing the tasks, kubelet does not restart. This PR fix this behavior

Users should opt in for features and not opt out.

After upgrading to newer Kubernetes(v1.17 at least), kubectl command
shows the following warning message:

  WARNING: Kubernetes configuration file is group-readable.
  This is insecure. Location: /home/foo/.kube/config

The kubeconfig was copied from {{ artifacts_dir }}/admin.conf with
kubeconfig_localhost feature. It is better to set valid file mode
at getting it on Kubespray.

If no_proxy_exclude_workers is true, workers will be excluded from the no_proxy variable.  This prevents docker engine restarting when scaling workers. (#6520)

Remove task with install etcdctl from etcd role when etcd_kubeadm_enabled=true

The CA cert was only deployed on master nodes

Added Comment line above checksum section to add clarification about Kubespray's version support and testing (#6785)

reset playbook fails and does not continue cleanup after for
example a host reboot with kubelet stopped/disabled

The 0d0cc8cf change creates several
DaemonSets to cover the Flannel CNI installation for different CPU
architectures. This change removes the unnecessary architecture value
from the docker tag value.

In case multiple nodeselectors are specified in ingress_nginx_nodeselector, the generated daemonset yaml template for nginx is invalid due to missing indentation starting with the second nodeselector

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.
