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)

The label triage/support has been reclassified as kind/support. The
kind/* family of labels makes more logical sense, as they describe the
"kind" of thing an issue or PR is.

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

If the `mitogen.yml` playbook is run, it installs Mitogen in this path, causing Git to believe there to 500+ changes. This simply excludes that external module from git

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.

I kept seeing `TLS handshake error from 10.250.250.158:63770: EOF` from two IP addresses that correlate to my ELB. Changing the health check from TCP to HTTPS stopped the errors from being generated.
