Since oslo-incubator is no longer maintained[1] after 90ae25e38915cc502d9e9c52d59e8fb668a72ae1. We should cleanup the deprecated code. This patch do the following cleanup actions: 1. Use magnumclient.i18n instead of magnumclient.openstack.common._i18n. 2. Use magnumclient.exceptions instead of the deprecated magnumclient.openstack.common.apiclient.exceptions[2].
