Add image_id as parameter to clone_image

Registered by Navneet on 2013-07-16

The clone_image method in VolumeDriver has volume and image_location as input parameters. This method also needs to have image_id as one of the inputs for clone_image implementations so as to use it in efficient cloning in scenarios where its required to introspect internal stores or catalogue for a particular image before performing efficient clone for it. Hence image_id needs to be added as additional param to clone_image method.
