Add nova migrate_version check to cinder import
Cinder-manage migrate import only works from Nova/Folsom--->Cinder/Folsom
this change adds an explicit check of the nova migrate_version (133)
to make sure we have all of the volume id/uuid changes that are needed
to be compatable, and presents an error message if that's not the case.

Clean up db.volume_create()
Adding the metadata return to db.volume_create() introduced some
messy and unnecessary repitition in the code. This patch
cleans that up and makes use of existing volume_get functions rather
than duplicating the code in volume_create.
This syncs cinder up with the patch as it's been submitted for nova
in https://review.openstack.org/#/c/10461/
Update quota when deleting volume that failed to be scheduled
If one volume was failed to get scheduled, removing such volume should
also clean up reservation.
Also when create_volume is ready to send to scheduler, reservation
should be committed no matter backend can successfully create that
volume or not since deleting volume call will do a minus reservation
even on volume with 'error' status.

Add a resume delete on volume manager startup
Currently if for some reason the volume service was stopped
during the zero out operation of a volume delete there was
no way to get the volume removed from the system (it would
be present in deleting status forever).
This change adds a simple check of volumes in the DB with status
of deleting, and if any are found it restarts the delete process
on them.
Removed the "vtype" option which did not work in the driver, and
added the "easytier" option. Added another check to _check_flags
and made sure -warning flag is passed properly. Added unit tests
to check all option variations.

Add update to volume and snapshot controllers
Add update method to api.openstack.volume.volumes and snapshots

the update method. Implementation closely matches updates to server

Nail the pip requirement at 1.1.
The most recent version of pip (1.2.1 as of a couple days ago) fails
to install the required Cinder .venv packages. Nailing the installed
pip version when using run_tests.sh seems like a reasonable solution
to this issue.

Don't zero out snapshot volume on snapshot_delete
When trying to zero out an LVM snapshot on precise the kernel sometimes
hangs when performing the dd. Also the dd process itself can take
an extremely long time even when it does succesfully complete.
This can be up to 30 minutes for a 1 Gig volume/snapshot.
I believe this is a kernel specific issue with LVM snapshots. The
zeroing process is unreliable and can cause kernel hangs to let's remove it.
In order to protect against data leakage we'll implement the zeroing process
on volume creation. This doesn't seem to have a significant impact and doesn't
suffer from the same isues tha zeroing out an LVM snapshot does.
No reason to continue zero on delete, the zero on creation should
probably be sufficient.
Doesn't seem to cause any timing issues but need to keep this in mind.

Recent changes to SolidFire API changed iqn format
The SF API initially didn't supply the in prefix so we
formed it manually in the OpenStack driver.
This has been fixed in the API so we dropped the manual
build of the prefix in volume create. Unfortunatly missed
the same case needed in create-from-snapshot.
Going forward we're adding running integration tests against
SF to catch this sort of thing.

Sync notifier changes from openstack-common
Syncs the following from stable/folsom:
c767e9b Add multiple-driver support to the notifier api.
Also remove notification_driver from cinder.flags. This should
have been done when first adopting this code from openstack-common
since the option is defined there now.
Note: I've left the cinder-specific change to use cinder's context
rather than openstack-common's context.
* remove _ec2_volume_get_query and _ec2_snapshot_get_query in
cinder.db.sqlalchemy.api, because they no longer be used in cinder.
* import openstack.commmon.utils.timeutils, because notify_usage_exists use it.

Handle missing 'provider_location' in rm_export.
Updates the remove_export function in the ISCSIDriver so that
it handles the case where provider_location isn't set on
a volume. This can occur if a volume is created but not exported.
The dd process when clearing volumes, was seen to starve
the system when writing to an iSCSI SAN connected over GigE.
So use O_DIRECT within the dd process so that the system
buffer cache is not impacted, which is generally the
best thing to do when streaming large amounts of data.
Also one could drop the I/O priority of the dd process
by prepending "ionice -c3". That would change the priority
from "normal" (best effort) to "idle", which means zeroing
will only proceed when there is no other I/O on the system.
It was thought best to leave scheduling decisions to the
system however, rather than specifying them explicitly.
