Stephen Finucane c128ae1969 trivial: Don't ignore missing resources
An openstacksdk 'find_foo' proxy method will return None by default if a
resource is not found. You can change this behavior by setting
'ignore_missing=False'. We were doing this in most, but not all cases:
correct the issue.

In the event of calling 'image delete' with multiple images, it will no
longer fail on the first missing image and will instead attempt to
delete remaining images before failing.
