merge vish's changes (which merged trunk and fixed a pep8 problem)

per vish's feedback, allow admin to specify volume id in any of the
acceptable manners (vol-, volume-, and int)

Also, have manager only attempt to export volumes that are in-use or available

update status to 'error_deleting' on volumes where deletion fails

s/cleanup/volume. volume commands will need their own ns in the long run

578. By Anthony Young on 2011-01-18

fixes related to #701749. Also, added nova-manage commands to recover
from certain states:

# Delete a volume that is in an error state
nova-manage cleanup delete_volume vol-id

# reattach a volume. this is typically required after a host reboot
nova-manage cleanup reattach_volume vol-id

Implement support for streaming images from Glance when using the XenAPI virtualization backend, as per the bexar-xenapi-support-for-glance blueprint.

Images may be streamed raw, or will be streamed into the right place to allow room for an MBR and partition table, if using non-raw images. PV vs HVM detection now occurs on the image, immediately after it has been streamed. External kernel / ramdisk are also supported in this mode.

Unit test changes include a partial Glance simulator, which is stubbed in place of glance.client.Client. This allows us to pass through the VM spawn path with either glance or objectstore backends enabled; the unit tests now cover both. A dependency upon glance has been added to pip-requires, in order to pull the Glance client code into the venv.

This includes minor fixes to nova.image.glance. This code is expected to be heavily reworked anyway with the image-service-use-glance-clients work.

Works around the app-armor problem of requiring disks with backing files to be named appropriately by changing the name of our extra disks.

disk is fine, as is disk.local and disk.rescue.

Add refresh_security_group_* methods to nova/virt/fake.py, as FakeConnection is the reference for documentation and method signatures that should be implemented by virt connection drivers.

This removes the need for the custom udev rule for iscsi devices. It instead attaches the device based on /dev/disk/by-path/ which should make the setup of nova-volume a little easier.

Risk of Regression: This patch don’t modify existing functionlities, but I have added some.
    1. nova.db.service.sqlalchemy.model.Serivce (adding a column to database)
    2. nova.service ( nova-compute needes to insert information defined by 1 above)

So, db migration is necessary for existing user, but just adding columns.
