Loosen anyjson dependency to avoid clash with ceilometer
Ceilometer depends on anyjson 0.3.1, whereas cinder requires
exacly 0.2.4.
The net effect is a devstack with ceilometer installed will
appear to work initially, as ceilometer is sparked up after
cinder. However, if any of the cinder services are subsequently
restarted, they fail with:

Configuration Options clean up
Small clean up of configuration options including:
* unused config opts:
- reclaim_instance_interval
* rename 'instance' in config opts name/help message to 'volume'
- 'instance_usage_audit_period' to 'volume_usage_audit_period'
- help message of 'volume_name_template'
This change also re-generates cinder.conf.sample file.
This ensures that we fail-fast if the tgtd configuration does
not include the directory for volume iscsi target configs,
instead of only blowing up when tgtd is restarted.

Remove unused code: check_for_export.
This code has been unused since cinder was split from nova. It used to
be used as a safety check during live migration. The check was removed
recently in nova, since it wasn't being used with Cinder anyway (just
nova-volumes).
An alternative approach would be to expose this from Cinder somehow if
we feel it's important, but until then, there's no reason to keep dead
code around.
This patch syncs the cinder driver code with that of the nova code,
as we received comments in the review process there. All changes are
minor: (1) removing unnecessary type checks of the flags, (2) not
using getattr to access the FLAGS, and (3) using the self.flags()
infrastructure that test.TestCase provides.
Currently nova and cinder have to have the same set of az's for
the ec2 api to work properly. Therefore, set the default az for
cinder to nova so they will match.
Includes a hack to az to set cinder to nova to work around gate
issues. The hack can be removed once the gate sets the zone to
nova properly.

Add lun number (0) to model_update in HpSanDriver
The HpSanDriver was not setting the lun number in model_update
and as a result default value of 1 was being used. Trouble is the
Lun number used by LeftHand is 0, so the connect info would be
wrong and fail when trying to attach the volume.
Even when the san_is_local config option was set to false, the
SolarisISCSIDriver's _execute method was accidentally set to
util.execute by the VolumeDriver's __init__ method.
The code in nova for logging added an extra root handler to be
able to log messages to the console during log setup. This handler
was removed in the setup method. The common setup method no longer
removes this handler, so don't create it. Note that there may be
a small period before the logging setup is finished where messages
will not appear.
Python ignores SIGPIPE on startup, because it prefers to check every
write and raise an IOError exception rather than taking the signal. Most
Unix subprocesses don't expect to work this way. This patch (adapted
from Colin Watson's post at http://tinyurl.com/2a7mzh5) sets SIGPIPE
back to the default action for cinder.utils.execute and cinder-rootwrap
created subprocesses.

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)

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

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.

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.
