Refactor reschedule in exception handling of volume manager
Previous exception handling has a pitfall that may potentially clear
the sys.exc_info() (by calling SQLalchmey to update db). This patch
refactors some part of exception handling in create_volume() to make
sure sys.exc_info() is retrieved so that we can log and reraise it;
also we make sure exception be reraised at the end of exception handling
no matter the request is rescheduled or not.
As a side effect, we fixed a bug in unittest which didn't provide
correct argument to db API but previously this exception has been wrongly
consumed by volume manager's exception handling (not reraise exception
when request is rescheduled).
Current codes in create_volume() may exists a scenario that
a context which is not elevated but after it fails in volume
creation, it becomes elevated. This patch saves original
context, so that if it fails in volume creation simply use the
original context for further scheduling.

Add execute wrapper to brick LVM code.
Add an execute wrapper to the brick lvm code and
enable the ability to pass in a desired executor other
than just using the default common/processutils executor
if there's some reason to do so.

driver to continue using cinder/utils execute until we switch over

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.
Updates the os-services API extension so that it is consistent
internally (index and update return similar formats), and so
that it works with the following cinderclient code changes which sends

{"binary": "cinder-volume", "host": "host1"}
It addresses a similar issue which happens in nova os-services extention
before. https://bugs.launchpad.net/nova/+bug/1147746
This change added 'binary' key in request and 'status' key in response
while still keeping 'service' ane 'disabled' key for API compatibility
sake.

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,

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

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.
