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.

iSCSI LUN wasn't being removed from the system until the very

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

that content_length cannot be determined. Since the content length is already
computed in backup/services/swift it shouldn't be a problem to set this
parameter.

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

raise e

store information about exception then do all actions and then
reraise it. This is caused by eventlet bug. It lost information

This way at least if some one makes an improvement to the nova
test framework cinder can improve here also.
Note that now all the tests a thread safe. Added a concurrency argument
to run_tests.sh that defaults to 1. You can specify your own level then
and take the risk of intermittent failures. Tell jenkins to use a
concurrency level of 1 to avoid failing gate jobs.
