Requesting a List of Public VM Images

We want to see a list of available virtual machine images that the Glance server knows about.

We issue a GET request to http://glance.example.com/images/ to retrieve this list of available public images. The data is returned as a JSON-encoded mapping in the following format:

{'images': [
  {'status: 'active',
   'name': 'Ubuntu 10.04 Plain',
   'disk_format': 'vhd',
   'container_format': 'ovf',
   'size': '5368709120'}
  ...]}

All images returned from the above `GET` request are public images
