Currently the project-deploy-guide links to the entire dev
doc repo for Kolla-Ansible. This is incorrect. It should link
only to installation information that can be found in the quick
start guide. This patch remedies that change, and ensures that
there is a link to the kolla deploy guide published at
docs.o.o.

Closes-Bug: #1614572

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.
