Update/Publish volume service updates on delete.
The Filter scheduler weighing function was failing because
we were only updating the capacity info either on the periodic
60 second interval or after succesful creates.
The result was that if you exceeded your capacity within the
update interval you would no longer be able to create volumes even
if you deleted existing volumes until the update was performed and
published.
Since we're updating on on create, there's no reason why we shouldn't
do the same on delete for the applicable volume-service.
The periodic updates are still important for other purposes so they're left
alone, but with this change we keep things up to date so the filter scheduler
has the correct picture of the world.

solidfire: Add ability to override account prefix
The SolidFire account is created with a prefix based on the hostname
of the host running cinder-volume. This prevents cinder-volume from
being run in an active/active setup.
This patch introduces a new configuration option sf_account_prefix
to override the prefix used when a SolidFire account is created.
If sf_account_prefix is empty, no prefix will be added to
the SolidFire account name when created.

Create an LVM utility to use for local storage.
This adds a simple LVM class for performing local

of PV's to use in creation.
See BP for information on where this is going and

Add CINDER_LOCALEDIR env variable
Part of fixing bug #995287
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 cinder
modules are imported since some modules attempt to translate strings
at import time (e.g. in cinder.flags). This is broken and inefficient,
but fixing it involves adding something like sphinx's l_() function and
would be very invaisve.

Remove gettext.install() from cinder/__init__.py
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.
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 Cinder, we have taken a shortcut to avoid having to call it
explicitly from each script and instead call it from cinder/__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 cinder code (indeed, if we wanted
to support this, Cinder 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
cinder.openstack and this in turn causes gettext.install('cinder') 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.
However, there's a bit of an annoying detail here - by default,
nosetests starts in the current directly and tries to import all modules
it finds to look for tests. Without the _() builtin installed, importing
some modules like cinder.flags will fail.
Since it only ever makes sense to load tests from the cinder/tests dir,
we can ask nose to do that by using the --tests argument via setup.cfg.
This patch fixes the ability to set the volume_backend_name
for each driver. The original bug was filed against LeftHand
and 3PAR, but several drivers exhibited a fixed backend name.

Deleting a backup removed the backup record from database
Instead we should be marking the backup as deleted so that we have an audit
of all the backups. Backups are now marked deleted in the way that volumes
are.
This method is buggy because it works only on host machine with english language, and
apparently this method is also useless because we don't need to check if a path exist if
we can use command option -p for "mkdir" command and option -f for "rm" command.
If the CinderVolume service is restarted while an image-copy is
happening, the volume gets left in a 'downloading' state and
cannot be used or deleted. This fix adds code to init_host to
look for volumes (on this host) in such a state, and move them
to an error state. It also calls clear_download in the driver
in case the driver needs to perform an action, such as
detaching the volume.
