    libvirt: Make behavior of os_require_quiesce consistent
    
    Currently, os_require_quiesce metadata is used in two meanings.
    For volume backed instances, quiescing is always tried on
    snapshot, and the metadata specifies whether snapshot should
    be aborted if quiescing is failed. For image backed instances
    in the libvirt driver, the metadata determines whether quiescing
    is invoked or not.
    
    To make the behaviors consistent, this introduces the same logic
    as volume backed instances into libvirt image snapshotting.
    
    This also fixes AttributeError during live snapshot introduced by
    commit 4f43bbafa4bfc2ab149d5db4eb55320c1602658b.

Title:
  Quiescing instance on live snapshot fails by AttributeError

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  *Step to reproduce:

  - Enable live snapshot by adding following lines to nova.conf:

  [workarounds]
  disable_libvirt_livesnapshot = False

  - Boot instance from image with hw_qemu_guest_agent=yes and
  os_require_quiesce=yes properties.

  $ glance image-show f22-qga
  +--------------------------------+--------------------------------------+
  | Property                       | Value                                |
  +--------------------------------+--------------------------------------+
  | Property 'hw_qemu_guest_agent' | yes                                  
  | Property 'os_require_quiesce'  | yes                                  
  ...

  $ nova boot --image f22 --flavor m1.small f22-1

  
  - Create an instance image

  $ nova image-create f22-1 f22-img

  
  - Image creation fails with the following error:

  File "/opt/stack/nova/nova/objects/image_meta.py", line 103, in from_dict
       image_meta.get("properties", {}))
   AttributeError: 'ImageMeta' object has no attribute 'get'
