Public bug reported:

When using a compressed image format it's possible to have late boot
failures because the expanded image can't fit on disk. Horizon should
show a specific error message for this failure.

To create:
use Admin->System->Image->Create Image
Download a largish compressed image such as:
http://cloud-images.ubuntu.com/trusty/current/trusty-server-cloudimg-i386-disk1.img
Format QCOW2
Copy Data: true
Public: True

This disk is a compressed image which takes 241M, but expands to 2.2G
ubuntu@unbuntu-drf-3:/opt/stack/data/glance/cache$ qemu-img info a22f195e-e64a-4170-90ff-e76f49a3d6f8
image: a22f195e-e64a-4170-90ff-e76f49a3d6f8
file format: qcow2
virtual size: 2.2G (2361393152 bytes)
disk size: 241M
cluster_size: 65536


Launch an Instance based on this image
Project->Compute->Instances->Launch Instance
Choose m1.nano, m1.tiny, or some other flavor with not enough disk
Boot From Image (creates new volume)

It fails with an obscure error message.

We should catch the exception related to this specific circumstance and
show a relevant error message.
