Adding -e REGISTRY_PROXY_REMOTEURL=https://registry-1.docker.io to the
docker run command in the start-registry script configures the local
registry as a pull through cache. However, pushing of images to the
local registry fails.

Pushing to a registry configured as a pull-through cache is unsupported.
For more information, reference the proxy section in Docker
Documentation (https://docs.docker.com/registry/configuration/)

The start_registry script has been updated in the patch set
https://review.openstack.org/#/c/426338/

This builds the deployment guide that will be published to
https://docs.openstack.org/project-deploy-guide/newton/.

In this approach, all existing documents in kolla-ansible/doc directory
will remain. The kolla-ansible/deploy-guide directory will simply
include all documents that exist in the kolla-ansible/doc directory.
All new changes will be made to the documents in the docs directory
which will be imported to the deployment-guide. However, I believe we
will also have to build the deployment-guide every time a change is
merged to the docs in the doc directory.
