test_volume unittest fails if ran only this module
Using stevedore ExtensionManager to load entry_points(extensions)
before running any test case.
In BaseVolumeTestCase we have stubbed 'os.path.exists' call,
because of this stevedore is not able to load entry points paroperly.
Stevedore internally use pkg_resources and pkg_resources use
'os.path.exists' to check if entry_points.txt file exists or not.
Because of stubbibg it is returning True even if file do not exists.

Check type argument on create from source and snap
Currently the create from snap and create from source
options will set the volume-type when specified in the
create call.
This is actually wrong, because clone and create from snap
MUST be performed on the same backend as the parent volume. The
result is that if the specified type doesn't match the specs for
it's parent, and actually needs to be on a different backend
the new volume will "appear" to have the correct type, but it's
actually invalid.
The --volume-type argument should be rejected when --source-volid
or --snapshot-id are used, and the parent type-id just picked up
and used. Then the user can retype if desired.
Auto failing this strictly causes backward compatability issues though
so we'll just check for a mismatch and raise an exception in that case.
This way if the user knows what they're doing and they're explicit
in the command we still allow it and things are fine.

New HP LeftHand array iSCSI driver
This driver is intended to replace the current OpenStack Block
Storage HP LeftHand (LH) StoreVirtual iSCSI Driver,
(cinder.volume.drivers.san.HpSanISCSIDriver), by moving the
existing SSH interface into the new driver to maintain backwards
compatibility, and add the new LH REST interface for new driver
features.
We have the driver broken into 3 files:
hp_lefthand_iscis.py (common interface)
hp_lefthand_cliq_proxy.py (old SSH interface)
hp_lefthand_rest_proxy.py (new REST interface)
The reason we are doing this is because the SSH interface on LH
array has connections and performance limitations. These problems
will be resolved by moving to the new LH OS REST interface. Also,
new LeftHand array capabilities will only be supported in the
REST(hplefthandclient) interface.
To support new driver capabilities (create cloned volume), the
python REST client (hplefthandclient) is required and can be
downloaded from the pypi repository:
http://pypi.python.org/pypi/hplefthandclient.
This REST client requires LeftHand firmware version 11.5 or
greater.

Allow operators to customize max header size
HTTP messages max header line size has been increased from 8K to 16K
by default to allow using tokens including up to 14-15 catalog
entries. The same issue
(https://bugs.launchpad.net/swift/+bug/1190149) may occur again in
the future, if keystone's catalog grows further.
Allowing operators to customize the max header size, will allow them
to have Cinder working whatever the size of the catalog (if the option
is properly set).
It appears that there are certain cases where a detach
and a delete call can overlap causing a race in the
remove_iscsi_target method. The result is that when
the slower method gets around to the final removal of
the persistence file it's no longer there, so we
hit an unhandled exception.
This patch does two things:
1. It adds the volume lock to the detach_volume
method in the manager (already in place for delete).
This should mitigate the race and allow us to avoid it.
2. In the iscsi_remove_target method check if the
persist file has already been removed when we get
to the last check. The fact is that if it was somehow
removed before we got here we don't really care, we're
just going to delete it anyway.

Remove tox locale overrides
* tox.ini: The LANG, LANGUAGE and LC_ALL environment overrides were
introduced originally during the testr migration in an attempt to be
conservative about the possibility that locale settings in the
calling environment could cause consistency problems for test runs.
In actuality, this should be unnecessary and any place where it does
cause issues ought to be considered an actual bug. Also, having
these in the configuration actively causes older pip to have
problems with non-ASCII content in some package metadata files under
Python 3, so drop it now.

Storwize/SVC: Fix races in host-related functions
In the Storwize/SVC driver, initialize_connection checks if a host
object exists on the storage, and if not, creates one. Similarly,
terminate_connection checks if there are any more mappings for this
host, and deletes the host object if there are none. Consequently, there
exist races between two initialize_connection calls, two
terminate_connection calls, or one and one.
The easy solution here is to use locks. Because locks are files on the
local machine, this implies that all cinder-volume processes managing a
given Storwize/SVC contoller run on the same machine.

Dont set error_extending status on API extend call
Recent change (Ifd523ac5e9039861cf87711dc5c4842b5cb524c2)
moved the quota check on extend_volume to the API layer
in order to provide feedback to caller if the quota check
failed.
The problem is that change still sets the volume status to
error_extending if the quota check fails. There's no reason
to do this if we're now giving immediate feedback that the call
failed.
I'm also unclear on what the purpose of adding the reservations
to the rpc call are, but I'll double check on that before changing.
This patch leaves most of the previous change in place but
removes the setting of error_extending to the volumes status
on the quota fail.

Remove create_export from volume create
Currently the LVM driver creates iscsi targets on
volume creation, even though it's only used at
attach time. This isn't necessary and in fact
causes issues if a volume is extended because the
target information isn't currently updated after the
extend. In addition a number of other drivers inclduing
the LIO iscsi driver require the target be created with
initiator info, so the tgt that's created initially
again isn't valid.
This change removes the create_export call from the
volume create process and makes it part of the
managers intialize_connection routine which is
more appropriate.
This change also removes the target on detach since
it's not used any longer and again as the volume may
be modified or extended.
Time unit is missing in the description of vmdk driver option
"vmware_task_poll_interval". Due to this, the vmdk driver config
reference document doesn't have the timeunit in its description
column. This fix adds the missing time unit (seconds) in the
driver option.
