and coredns gets improperly scaled back up to 2 replicas.

* 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
We don't need to support upgrades from 2 year old installs,
just from the last major version.
Also changed most retried tasks to 1s delay instead of longer.
* Use K8s 1.14 and add kubeadm experimental control plane mode
This reverts commit d39c273d96.
* Cleanup kubeadm setup run on first master
* pin kubeadm_certificate_key in test
* Remove kubelet autolabel of kube-node, add symlink for pki dir

* Adding ability to maintain existing Encryption Secrets at Rest.
If secrets_encryption.yaml is present it will not be overriten with a new kube_encrypt_token.
This should allow for it to be set ahead of a playbook running or maintain it if cluster.yml is ran on the same cluster and the ansible host does not have access to the secrets.
* Setting existing kube_encrypt_token across all master nodes in case it was missing in one or more nodes.
