* Grouped documentation articles into several main parts: user docs,
admin docs, developer docs.
* Changed the index page so that it contains links to the index pages
of the main documentation parts like user docs, admin docs etc.
* Fixed all the broken links
* Removed index generation since it's not informative at all in its
current form and it exposes code internals (REST controller class
names)
* Removed obsolete properties that are no longer used by the
"openstackdocstheme" project
* Removed obsolete static html files
* Moved part of the images to the folders where they are used
Further work:
* Refactor main chapters (user, admin, developer) one by one and
make them look consistent. For example, there are several pages
that provide similar kind of information: overview, quick start,
main features etc. It is a mess that's been accumulated throughout
the last 4-5 years.
* Fill the gaps. Add all missing pages like: event notifications,
workflow environment, etc.
* Move cookbooks from Wiki to this doc.
