CoraidDriver: Create_volume_from_snapshot of a different size
When you create a Volume from a Snapshot, the 'size' argument for the
new volume isn't used at all.
So, the new volume created will be created (successfully but) with the
same size as the snapshot size.
Cinder think the volume has been created with the right size.
We just need to call Coraid ESM LV Resize with the REST API after
the volume has been created.

hp3par_domain will remain in the config for now and will be

Save some more image attributes to volume_glance_metadata.
Current issue: When copying an image to a volume, attributes like size, disk_format, container_format,
checksum, min_disk and min_ram have not been copied so far. When booting a VM from a volume, we are
not able to check these atrributes without giving the image id. Furthermore, if the original
image is deleted, we will lose all the information.
This patch saves these attributes into volume_glance_metadata. We can still check these attributes
without giving the image id when booting a VM from a volume.

Fix check_for_setup_error for sheepdog driver
Current implementation of check_for_setup_error() of sheepdog driver
cannot work correctly with the latest version of sheepdog cluster.
This patch fixes it and adds tests for both old and new version.
This patch adds the new brick initiator connector object
which contains the code to do volume attach and detach to a host
machine. It includes hooks to work in both cinder and nova.
Nova has different exec wrapper and it also needs to talk to a
hypervisor at certain points during detach.
This patch also pulls the copy/pasted code from nova in the base
ISCSIDriver's _attach_volume method to use this new brick library.
This patch also includes a fix in the ISCSIDriver's
copy_volume_to_image code that didn't actually detach a volume
when it was done with the operation.

Radosgw returns a "411 Length Required" in case the content-length is not

Replace glance_metadata check with bootable column.
This patch adds a column to indicate if a volume is bootable or not.
Cinder API V1 was using get.volume_glance_metadata to determine
if a volume was bootable for translate_view.
This is fine until you put a heavy load on the system and things
can fall apart, particularly the backref of the glance meta is no longer
available and the call blows up. Also this results in a bit of extra
unnecessary data being passed around with every create and get call.
This is especially an issue when creating hundreds or thousands of volumes.
Even better we can now reliably create thousands of volumes.

Do not raise NEW exceptions
Raising NEW exception is bad practice, because we lose TraceBack.
So all places like:

raise e

If we are doing some other actions before reraising we should
store information about exception then do all actions and then
reraise it. This is caused by eventlet bug. It lost information
