* 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
