    Refactor glance id<->internal id conversion for s3

     * Moves nova.image.s3.S3ImageService functions for converting
       between glance ('image_uuid') and internal (db) ids to ec2utils:

           get_image_id => ec2utils.glance_id_to_id
           get_image_uuid => ec2utils.id_to_glance_id

     * Refactors ec2utils.glance_id_to_id to create a new S3Image
       object associating a glance id to an internal id if such a
       mapping does not already exist. Previously, only calls to
       nova.api.ec2.cloud.CloudController.describe_images would
       add new mappings, but now any attempt to convert a glance id
       to an internal id will succeed, resolving bug 948286.

     * Adds 2 convenience methods to ec2utils, as per bcwaldon:

           ec2_id_to_glance_id
           glance_id_to_ec2_id

     * Since this is a strict refactor and only streamlines existing
       well-tested functionality, this change includes no new tests.
