Fix OverLimit's message

When creating image, _update_with_data failed and in
/var/log/glance/api.log there was log "Image storage media
is full: There is not enough disk space on the image
storage media."(ref: https://github.com/openstack/glance/
blob/aba79f0d2e75731fa363d8df6d3c7c095ecfac8c/glance/
api/v2/image_data.py#L196)
But tempest raised OverLimit exception with message
"Quota exceeded" which was misleading.
So this is to fix OverLimit message to make it clearer.
