Description:
- Changes in 'glance/glance_store/_drivers/aws.py' are required because
when glanceclient tries to retrieve image details, it expects 2 values.
But in the current case, it was yielding a tuple which was throwing
exception as it was getting only 1 value when 'get()' was called
- Added a function "clone_image()" which takes volume details, image
metadata, object of glance service, image location as arguments.
- Steps:
1. get image details from AWS using image id provided in image metadata
and get snapshot id from response. If snapshot id is None, then raise an
exception
2. create a dict object which contains size, zone and snapshot id as
fields
3. call create_volume() with dict created as argument
4. create tags for volume created
