    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.
    
    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.
    
    Fixes bug 1186401
