Support to backup for instance that boot from volume

Registered by Jay Lee

It support to backup for instance that was made by 'auto-create-boot-volumes' features.
There is different between normal instance and instance using 'auto-create-boot-volumes'.
normal instance's root volume is just file. For example, /var/lib/nova/instances/instance-XXXXXX/disk
but root volume of instance using 'auto-create-boot-volumes' is a device. For example, /dev/disk/by-path/ip-10.245.34.2:3260-iscsi-iqn.2003-10.com.lefthandnetworks:cxx-zxx-:611:cxx-pxx-lun-0
In backup logic, instance's root volume can be snapshot using qemu-img. But It cannot execute to instance using 'auto-create-boot-volumes'. because root volume is a device, not a qcow2 file.
So, This blueprint add some command for backup instance using 'auto-create-boot-volumes'.

This looks good, but will probably have to wait for folsom.

FYI, this is going to be a little more complicated with the cinder breakout, so it may take some thinking to decide how it should be done.

I think this is unlikely to make folsom. --Vish
