Unauthorized message isn't consistent with client-API doc

When exception "unauthorized" occurs, if auth_version is keystone V3, the message "Unauthorized. Check username/id, password, tenant name/id and user/tenant domain name/id" will be returned as response.

In the client-api document(see http://docs.openstack.org/developer/python-swiftclient/client-api.html#keystone-v3), for keystone V3, these parameter are being used as follow:
user_domain_name, project_domain_name, project_name,
user_domain_id, project_domain_id and project_id

And the tenant name/id has been deprecated in keystone V3. The message should be change to "Unauthorized. Check username, password, user domain name/id, project domain name/id, project name/id".
