* Add kubelet config

* Change kubelet_authorization_mode_webhook to true

* Fix lint

* Sync env file

* Refactor the kubernetes node folder

* Remove deprecated flag and fix lint

* Download to delegate and sync files when download_run_once

* Fail on error after saving container image

* Do not set changed status when downloaded container was up to date

* Only sync containers when they are actually required

Previously, non-required images (pull_required=false as
image existed on target host) were synced to the target
hosts. This failed as the image was not downloaded to
the download_delegate and hence was not available for
syncing.

* Sync containers when only missing on some hosts

* Consider images with multiple repo tags

* Enable kubeadm images pull/syncing with download_delegate

* Use kubeadm images list to pull/sync

'kubeadm config images pull' is replaced by collecting the images
list with 'kubeadm config images list' and using the commonly
used method of pull/syncing the images.

* Ensure containers are downloaded and synced for all hosts

* Fix download/syncing when download_delegate is a kubernetes host

add the support of the folling property in azure-credential-check.yml
  - azure_loadbalancer_sku: Sku of Load Balancer and Public IP. Candidate values are: basic and standard.

  - azure_disable_outbound_snat: disables the outbound SNAT for public load balancer rules

Both kubedns and dnsmasq modes are long not maintained.
We should run dns_late steps at the end because sshd
makes DNS lookups during Ansible run and has 2s timeouts
for each failed lookup trying to connect to coredns before
it is ready.

This was already approved in #4106 but there are CI issues
with that PR due to references to kubernetes incubator.

After upgrading to Kubespray 2.8.1 with Kubeadm enabled Rook

being correct. Adding the var fixed the issue

Addressing the discussion started in #4064, this PR moves kubeadm and
hyperkube binaries to /usr/local/bin before running them on the master
nodes.

It is to address the case where local_release_dir points to /tmp
(kubespray default) and /tmp is mounted with noexec mode, preventing
any binaries to be run in that partition.

In role "node", we still move kubeadm to bin_dir only on the worker
nodes.
