Fixes: bug #1179008
Using of locals() for formatting string is a nasty thing because:
1) It is not so clear as using explicit dicts
2) It could produce hidden errors during refactoring
3) Changing name of variable causes change in message
4) Creating a lot of unused variables

Syncs these two commits from oslo-incubator:
Support overriding oslo localedir too
Add a gettextutils.install() helper function
to get a new gettextutils.install() function which allows the default
localedir to be overwritten via an environment variable.
Note that gettextutils.install() must be called before any other nova
modules are imported since some modules attempt to translate strings
at import time (e.g. the 'message' attributes on classes in
nova.exception). This is broken and inefficient, but fixing it involves
adding something like spinx's l_() function and would be very invaisve.
Also, note that calling gettextutils.install() in nova.cmd.__init__
means that no program which uses a different translation domain should
ever import any of the modules under nova.cmd.
Change-Id: I86562b3a65d371673bb21f7179eecc7602bc0775
The gettext.install() function installs a builtin _() function which
translates a string in the translation domain supplied to the install()
function. If gettext.install() is called multiple times, it's the last
call to the function which wins and the last supplied translation domain
which is used e.g.
>>> import os
>>> os.environ['LANG'] = 'ja.UTF-8'
>>> import gettext
>>> gettext.install('keystone', unicode=1, localedir='/opt/stack/keystone/keystone/locale')
>>> print _('Invalid syslog facility')
無効な syslog ファシリティ
>>> gettext.install('nova', unicode=1, localedir='/opt/stack/nova/nova/locale')
>>> print _('Invalid syslog facility')
Invalid syslog facility
Usually this function is called early on in a toplevel script and we
assume that no other code will call it and override the installed _().
However, in Nova, we have taken a shortcut to avoid having to call it
explicitly from each script and instead call it from nova/__init__.py.
This shortcut would be perfectly fine if we were absolutely sure that
nova modules would never be imported from another program. It's probably
quite incorrect for a program to use nova code (indeed, if we wanted to
support this, Nova code shouldn't use the default _() function) but
nevertheless there are some corner cases where it happens. For example,
the keystoneclient auth_token middleware tries to import cfg from
nova.openstack.common and this in turn causes gettext.install('nova')
in other projects like glance or quantum.
To avoid any doubt here, let's just rip out the shortcut and always
call gettext.install() from the top-level script.

A new scheduler filter that allows the creation of instances from
specific tenants in selected aggregates.
With this filter is possible to isolate tenants in a specific set
of compute nodes (aggregates).
If a host is in an aggregate that has the metadata key
"filter_tenant_id" it can only create instances from that tenant(s).
A host can be in different aggregates.
If a host doesn't belong to an aggregate with the metadata key
"filter_tenant_id" it can create instances from all tenants.

This patch contains a number of cleanups of the nova devref,
mostly related to outdated content.
1) remove outdated todo items from network
=> these have been long covered in the manuals
2) remove outdated multinic docs and images
=> this is now better covered in:
http://docs.openstack.org/trunk/openstack-compute/admin/content

3) remove outdated cloudpipe docs, confs and scripts
=> This is now better covered in:

4) remove outdated networking docs

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

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.
