Matt Riedemann bc5ef2ff06 Remove cells v1 (for the most part) from the docs
As discussed in the mailing list [1] since cells v1
has been deprecated since Pike and the biggest user
of it (CERN as far as we know) moved to cells v2
in Queens, we can start rolling back the cells v1
specific documentation to avoid confusing people
new to nova about what cells is and making them
understand there was an optional v1.

There are still a few mentions of cells v1 left in
here for things like adding a new cell which need
to be re-written and for that I've left a todo.

Users can still get at cells v1 specific docs from
published stable branches and/or rebuilding the
docs from before this change.

Matt Riedemann 7c3c3b9863 Add contributor guide for upgrade status checks
This adds some background, guidelines and structural
notes on writing nova-status upgrade checks.

This is intentionally written with some potentially
redundant information or nova developers as it's
also meant to be consumed outside nova as part of the
community-wide "upgrade-checkers" goal for Stein [1].

Matt Riedemann 579e0cfd57 Document differences and similaries between extra specs and hints
Scheduler hints are not really documented very well at all except
for being mentioned per scheduler filter in the admin configuration
guide, nor are they documented within relation to flavor extra
specs which are both used for impacting scheduling decisions and
are choices that a deployer has to make based on how they configure
their cloud.

This change adds a document about scheduler hints and how they are
similar to and different from flavor extra specs, including end
user discoverability and interoperability, and thoughts on which
should be used if writing a custom scheduler filter.

The TODO in the API guide is also resolved by linking to this
document.

Eric Fried f9e13bcfed update_provider_tree devref and docstring updates
Design changes [1] from the Dublin PTG prompted some rewording of the
docstring for ComputeDriver.update_provider_tree.  And to avoid that
docstring becoming too enormous, relevant chunks of the spec [2] are
copied to a new devref document which is linked from that docstring.

There have been some major changes to how scheduling works in Nova
during the Pike and Queens cycles. This documents these design changes
so that this new, more complex workflow is clearly spelled out.

Sean Dague b9efc9d641 Create reference subpage
In an attempt to make the main navigation sidebar not be visual mud
(and really confusing) create a reference sub page that explains all
the references.
