Nexenta drivers ignore "does not exist" exception
Ignore "does not exist" exception in NFS and iSCSI driver,
delete_volume and delete_snapshot methods.
This exceptions means that the volume or the snapshot not exists in the
backend, so we can avoid "delete" errors, when the resource was already
deleted.

Add extend_volume for Huawei drivers
This patch adds extend_volume function for Huawei drivers.
Huawei T driver needs to create a slave LUN for the extended LUN.
And accordingly it needs to delete all these slave LUNs before deleting
the extended LUN.
HVS driver just sends a rest command to finish extending volume.

Fix lvm.extend_volume to pass Gig suffix
The extend function in the lvm driver was not converting
the cinder size value to Gigabytes before passing the call
to the vg module. The result was that we would attempt to
extend a volume to "new size in Megabytes" which of course
is less than the current size since we do a Gigabyte string
conversion on create and everywhere else.
This change makes sure we pass the integer change through
the sizestr method to get the G suffix needed to work properly.

FK lookup failures during migration
There are a couple of cases where migrations have failed
upgrading from Grizzly to Havana, this seems to be isolated
to a couple of migrations so far and the error message is a
failure to lookup/associate the volume-id FK dependency.
It appears that this is caused by not setting the charset
in the migration, so the result is that the initial db setup
uses utf8 and the migrations are using the default latin1.
This patch goes through all of the migrations in Havana that
specify InnoDB and explicitly sets the charset to utf8 to match
the volumes table (and the other original tables).

Fix Huawei drivers to support other host OSs
Huawei drivers create Linux hosts by default when attaching volumes.
This patch makes them also support Windows, XenServer, AIX, etc.
The default OS is still Linux if it is not specified.
Users need to configure the host OS types in Huawei XML configuration
file. They need to set the items like this:
<Host OSType="Windows" HostIP="10.10.0.1, 10.10.0.2, ..." />
<Host .../>
When attaching a volume, the driver will get the host IP from nova. We
compare that IP with the IP in "HostIP" to get the corresponding OS type.
VMware: Fixed upload-to-image for available volume
Cinder generally does not allow upload-to-image operation on a volume
that is 'in-use'. This can however be over-ridden using the '--force True'
flag. The VMware driver cannot support upload-to-image when the volume is
in-use. This is a restriction for the VMware driver alone. When the user forces
an upload on a volume that is 'in-use' the Cinder api layer sets the volume
status to 'uploading' and calls into the driver code to upload. In this
scenario the VMware driver needs to fail the operation.
The current driver code here does this check wrongly by looking for volume
status of 'in-use'. Fixing this check to identify an in-use volume correctly.

long flashcopy operation may block volume service
Storwize family uses flashcopy for snapshot or volume clone. The
volume delete has to wait until flashcopy finishes or errors out.
The _delete_vdisk() will poll volume FlashCopy status in a loop.
This may block volume serivce heartheat since it is in the same
. The solution is to use openstack FixedIntervalLoopingCall
to run the FlashCopy status poll in a timer thread.
The cinder volume mananger will resume delete operation for those
volumes that are in the deleting state during volume service startup.
Since Storwize volume delete may wait for a long time, this can cause
volume service to have long delay before it becomes available.
A greenpool is used to offload those volume delete operations.

Support Huawei driver upgrade from grizzly to havana
To make the driver upgrade from grizzly to higher versions, the patch
checks the old host name firstly when creating and deleting host in
Huawei storage system.
If the old host name exists:
*get and use it directly when adding host.
*delete it directly when deleting host.
The current implementation perform snapshot of attached volume.
This is invalid because when we take snapshot of the backing, the instance
continues pointing to the readonly delta and tries writing to it.
This patch will disallow snapshot creation of attached volume.
We have similar issue with delete of snapshot, when deleted the instance will
point to an invalid disk file, since that will get merged with its parent.
Hence any writes by the instance will fail with disk not found error.
This patch will ignore delete snapshot of attached volume.
Since we disallow snapshot of attached volume, we disallow linked clone of
attached source volume and also upload of attached volume.
