Public bug reported:

When modifying an image file and then updating the image by using glance  image-update --file <filename> <Image Name>
doesn't update the image 

How to reproduce
================
Download an image and upload it:

# wget http://download.fedoraproject.org/pub/fedora/linux/releases/21/Cloud/Images/x86_64/Fedora-Cloud-Base-20141203-21.x86_64.qcow2
# glance image-create --name fedora21b --disk-format qcow2  --container-format bare --is-public True --file /tmp/Fedora-Cloud-Base-20141203-21.x86_64.qcow2

Create some dummy file in /tmp/dummy and modify the image
#  virt-copy-in -a Fedora-Cloud-Base-20141203-21.x86_64.qcow2 /tmp/dummy /etc

Update the image:
#glance image-update --file Fedora-Cloud-Base-20141203-21.x86_64.qcow2  fedora21

Verify the image is not updated by comparing the checksum
# md5sum /var/lib/glance/images/bd84ac96-c2a8-4268-a19c-a0e69c703baf
# md5sum Fedora-Cloud-Base-20141203-21.x86_64.qcow2

When using --checksum the checksum in the image properties is updated but the the image itself  not:
#glance image-update --file Fedora-Cloud-Base-20141203-21.x86_64.qcow2 --checksum 2c98b17b3f27d14e2e7a840fef464cfe fedora21
