This is part of the blueprint vm-ensembles. The patch introduces the
group as a scheduler hint.
The patch set adds group support for multi-VM deployment. This is achieved
as follows:
1. A new hint is added: group. This will contain the name and type for the
group. At the moment only anti-affinity is supported. In the future
we will add network proximity. It will be extended to <name>:<type>
2. In order to ensure that group policy will be honored for future VM
deployments, the group is stored as system_metadata.
3. The anti affinity is implemented by a new filter called
GroupAntiAffinityFilter.

Hooks add the ability to insert custom code around operations that
declare a named hook:
e.g.
@hooks.add_hooks('create_instance')
def create_instance(....):
....
The above hook allows Hook objects to be run 'pre' and 'post' the
execution of create_instance()
Hook objects are discovered via the setuptools entry point group
'nova.hooks'.

Host state capabilities include multi-level information, like
cpu features are presented in capabilities:cpu_info:features, cpu
core number in capabilities:cpu_info:topology:cores.
Multi-level capability check maybe helpful in some situation, like
user want to make sure host support SSE3 instructions or AES-NI, or
user want to make sure the host has >4 cores for SMP instance. Current
capability filter does not support these requirements.
To support multi-level check, also add scope to capability filter,
so, now capability filter will handle no-scope extra_specs, or scope-format
as "capabilities:xxx:xxx" etc.

This removes the majority of the nova-volume code from the codebase.
It updates relevent config options to default to cinder. It updates a
number of existing tests that were depending on code that was removed.
A few things still need to be removed:
* volume/driver.py & volume/iscsi.py
These files are used by the libvirt volume driver tests. These
tests should be updated to mock the relevant calls.
* scheduler/simple.py & scheduler/multi.py
These files should no longer be necessary so they can be removed
in a subsequent patch
* exception.py cleanup
Once the above files are removed there are a number of unused
exceptions which can be removed
* database calls and database tables
The database calls have not been removed and the tables have not
been dropped. This can be done in a separate migration
* additional config options and nova.conf.sample
There may be a few extra config options that can be removed and the
conf sample can be regenerated

In file doc/source/devref/development.environment.rst added packages

to enable the dev environment to be setup. Without these run_tests.sh

There are several new operators added for extra_specs that are used
in compute capability filter and aggregate filter. These are
described in document in this patch. Fixed bug 1047036.

As noted in the bug report, without libxml2-dev and libxslt-dev
installed on ubuntu 12.04, the virtualenv creation will fail.
This fix simply adds the packages to the first
"Install the prerequisite packages." line

Commit d39137fa added functionality to the ComputeFilter to filter on
architecture, hypervisor_type, and vm_mode. The existing ArchFilter
already filtered on architecture. This patch merges the ComputeFilter
functionality introduced in d39137fa with the ArchFilter to create the
ImagePropertiesFilter. The ImagePropertiesFilter uses image properties
specified in the request_spec to filter hosts.
This patch also adds the ImagePropertiesFilter to the list of default
filters specified by the scheduler_default_filters FLAG.
Fixes LP Bug #1037339

The FilterScheduler doc was overlooked when new filters were added
or existing filters were changed. This change updates the doc with
information skimmed from the individual filters.
nova.conf.sample is updated as well with the current list of default
filters.
