Public bug reported:

we are able to destroy an instance when taking a snapshot.

the new image status would depend if it was already created and uploaded
to /var/lib/glance/images

I think that if we allow to destroy the instance when taking the
snapshot we run the risk of data corruption on the new snapshot or the
snapshot not being created at all.

so I think that to destroy the instance while taking the snapshot we
should have a --force in while the admin user knowingly destroys the
instance.
