Deploy guides includes quickstart guide.
Includes respect relative paths, but when
quickstart includes vagrant doc, deploy-guide
tries to locate the doc in its doctree (deploy-guide/source).

This causes error 404 and deploy-guide post-gates to fail

Checking http://files.openstack.org/docs-404s/2017-09-08.txt the link
/kolla-ansible/latest/quickstart.html gives a 404 and is most wanted.

The link now is /kolla-ansible/latest/user/quickstart.html - let's
update in tree docs for this.

Fix other broken links as well - with using intra-links instead of
external links - this will make it easier to notice breakage when files
are moved.
