    Remove broken config_drive image_href support.
    
    image_href support has not been working since at least shortly before
    Folsom release.  This is a good indication that this functionality is not
    used.  As far as I can tell, the docs also do not match what was
    supported.  An image ID was required, but docs show examples with full
    hrefs.
    
    DocImpact
    
    http://docs.openstack.org/developer/nova/api_ext/ext_config_drive.html
    
    References to supporting image_hrefs should be removed.
    
    Docs also state that 'true' or 'True' (depending on if you use
    XML or JSON) or empty strings are returned for detail/show.  The
    nova code seems to actually return '1' or an empty string or None.
    
    This has been corrected in this patch to return 'True' (always
    capitalized) or '' if it is enabled/disabled respectively.
    
    This patch also removes the hack that passed a config_drive_id via
    the Instance dictionary when config_drive_id is not a valid Column for
    Instance.
