* Merge OracleLinux in RedHat bootstrap-os

* Set default for use_oracle_public_repo in main.yaml

Allows to configure additionnal zone for domains not resolved by `upstream_dns_servers`.

* Add docker-ce 19.03 packages for Debian & Ubuntu

K8s has updated the recommended Docker version to 19.03. More
specifically it should be 19.03.4, but since we used 18.06.7 instead of
.2, I'm assuming the latest patch version should be used here as well.

* Add docker 19.03 for redhat

* Use k8s.gcr.io for kubernetes related images

* Use k8s.gcr.io in inventory sample

* Kubernetes 1.16.8

* Use 1.16.8 in sample inventory and kubespray-defaults

* upgrade metrics server and resizer images version

* scope "apps" api group for addon resizer

The 'regexp' parameter matches last occurrence of a line starting with 'proxy=' and replaces it with the one defined in 'line' parameter. If no match - it works same way as before. This fixes resuming cluster deployments failed after that task (if there was no more than one line starting with 'proxy' in the yum.conf file - this condition should also be reassured with the change introduced here) eg. if they were initiated with Terraform.

As the issue describes, when no external or local load-balanced is used,
kube-proxy won't be able to contact apiserver at 127.0.0.1. So the
config map should be left as is.
