docs title should include project name

[Radosław Piliszek]

Not much of a bug per se but rather request for improvement.

Currently all docs claim to be of OpenStack, the format is:
OpenStack Docs: <PAGE TITLE>
e.g.
OpenStack Docs: Deployment Guide
(even if it is of a particular project)

This hurts SEO and tab browsing as it is hard to recognize which pages belong to which project without opening page or looking at the url itself. It makes organizing bookmarks harder as well.

In the same vein, the title could include project version (release/cycle).
Plan minimum is:
OpenStack <PROJECT NAME> Docs: <PAGE TITLE>
e.g.
OpenStack Swift Docs: Deployment Guide

Plan extra is:
OpenStack <PROJECT NAME> <RELEASE NAME> Docs: <PAGE TITLE>
e.g.
OpenStack Swift Train Docs: Deployment Guide
or
OpenStack Swift Latest Docs: Deployment Guide
