euca-deregister deletes wrong image

[Tushar Patil]

Steps to reproduce:-
1) Create ramdisk, kernel, machine images using glance upload.

2) $euca-describe-images
IMAGE aki-00000002 (ipv6-kernel) private kernel
IMAGE ari-00000001 (ipv6-ramdisk) private ramdisk
IMAGE ami-00000003 (ipv6-disk-image) private machine aki-00000002 ari-00000001

3) Now try to deregister the ramdisk image using euca-deregister
$euca-degister ami-000001

Here I am trying to delete the machine image with id 1 which doesn't exists. So I was expecting euca-deregister should give me some error message. But in this case it actually deletes the ramdisk image ari-00000001.

removed mention of GlanceImageService because this is agnostic to the underlying image service...
