The development.environment instructions were almost completely copy/pastable
to get started on a new machine. Almost. This doc patch just adds python-tox to
the list of things to be fetched with apt-get, so now it's really *really* simple to get
started on a brand-new machine or cloud instance.

and additionally the examples have been updated to reflect the recent split

This patch makes the NUMATopologyFilter and instance claims on the
compute host use instance fitting logic to allow for actually packing
instances onto NUMA capable hosts.
This also means that the NUMA placement that is calculated during a
successfull claim will need to be updated in the database to reflect the
host NUMA cell ids the instance cells will be pinned to.
Using fit_instance_to_host() to decide weather an instance can land
on a host makes the NUMATopologyFilter code cleaner as it now fully
re-uses all the logic in VirtNUMAHostTopology and
VirtNUMATopologyCellUsage classes.

Allow extra spec to match all values in a list by adding the ALL-IN

Changes:

- modify match funtion to allow matching against a list instead of a
single value
- added new unit tests
- update devref documentation to reflect the new operator

This covers the plan for zero downtime upgrades. It looks at all the
building blocks we have in place, and a few we have planned for kilo and
pulls that into a process that we hope will deliver zero downtime
upgrades.
This is just an initial stake in the ground to help drive the upgrade
efforts during kilo.

The syntax suggested for adding hooks to nova via setup.py entrypoints is:
entry_points = {
'nova.hooks': [
'resize_hook': your_package.hooks.YourHookClass,
]
},
But this is incorrect. The proper syntax for an entry_points entry is:
entry_points = {
'nova.hooks': [
'resize_hook=your_package.hooks:YourHookClass',
]
},

At the nova mid-cycle we agreed that while specs have made our blueprint
process significantly better, we think the current approach still leaves
much to be desired. This document is the outcome of the discussion at
the mid-cycle on how we want to manage blueprints in Kilo.
This proposal is being placed in devref, as we want to use gerrit's
workflow (two core reviews, inline comments, revisions etc) and this is
a document for developers.
Introduce the idea of project priorities.

This patch adds the basic NUMA filter that will take the proposed
instance topology and try to match it against that of a host.
The matching will be done in the following manner:
* Filter will try to match the exact NUMA cells of the instance to those
of the host. It *will not* attempt to pack the instance onto the host.
* It will consider the standard over-subscription limits for each cell,
and provide limits to the compute host accordingly.
* If instance has no topology defined, it will be considered for any host.
* If instance has a topology defined, it will be considered only for NUMA
capable hosts.

It turns out adding the specs requirement to blueprints adds a
non-trivial amount of overhead, revisit when a blueprint and spec is
needed to minimize overhead in cases where it isn't helpful.

For some time, we've been informally implementing a "revert early"
policy around handling -2 worthy complaints after a patch has been
merged. These reverts can be contentious, so it's appropriate we make
it very clear what the policy and procedure here is in order to lessen
the contentiousness of these reverts.
