HDS Cinder Driver. Rev #1
blueprint hds-hus-iscsi-cinder-driver
This is the first rev of Hitachi Data Systems Cinder iSCSI driver.
This driver works with HUS (df850) array.
This driver contains all the base-line features specified for Havana release.

Update cloned volumes QoS settings.
The SolidFire device inherits all settings (including QoS) from

QoS to be updated when a clone was issued with a different Volume
Type than the parent volume it was never acted upon.
This change fixes that bug by simply adding the *new* qos settings

Fix ownership transfer when cloning with SolidFire
When cloning a volume with SolidFire driver, the owner of
the cloned volume is not set correctly in SolidFire when there is
a transfer of ownership.
This results in inconsistent states where the cloned volume
is owned by the new tenant in Cinder but SolidFire thinks it is still
owned by the original volume's tenant.
This patch adds the newAccountID parameter to all CloneVolume calls.
If the cloned volume is owned by the same tenant, newAccountID will
be set to the same value as the original SolidFire volume. There
will be no change of ownership done by the cloning process in SolidFire.
If the cloned volume should be owned by a different tenant, newAccountID
will be set to the appropriate SolidFire account corresponding
to the new tenant. If the SolidFire account does not exist already,
it will be created.

Make NFS share selection more intelligent.
Make the NFS share selection more intelligent by using a used_ratio
and oversub_ratio to determine the valid target. The used_ratio
is a hard-cap of maximum "actual" used space, oversub_ratio allows
for oversubscription of the share based upon the apparant-allocated
space for sparse files.
Removed Options: nfs_disk_util
New options added:
* nfs_used_ratio:
Float representation of the maximum allowed usage (e.g. 0.95
calculated by available_space / total_space) before the share
is no longer concidered a valid target. Default: 0.95
* nfs_oversub_ratio:
Float representation of the oversubscriotion ratio allowed when
utilizing sparse files (determined via "du"). This gets
multiplied against the total_capacity before comparing the
apparant space used by the backing volume files. Default
ratio is 1.0 (meaning reserved/allocated space cannot exceed
total space available on the mount).

Support mount options for NFS/GlusterFS volumes
This patch adds support for mount options for NFS/GlusterFS volumes.
To set options, append them to the line for the volume in the
nfs_shares_config or glusterfs_shares_config file:
192.168.175.166:/testvol -o backupvolfile-server=192.168.175.177
host1:/testvol2 -o backupvolfile-server=host2,rw,other_option
These options are used when mounting from the cinder-volume
service and the nova-compute service. (There is an associated
nova-compute patch to enable the same.)
This is a useful change for GlusterFS because the
backupvolfile-server option enables a mount to succeed even if
the first server specified is offline.

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.

localedir to be overwritten via an environment variable.
Note that gettextutils.install() must be called before any other cinder

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.
