From 8fdfd0f7ae809966e946b9425838e5c2c2fad215 Mon Sep 17 00:00:00 2001 From: chenjiankun Date: Mon, 20 Feb 2017 16:05:29 +0000 Subject: Add common method of openstack in openstack_utils JIRA: YARDSTICK-569 We have much redundancy code when using nova/neutron/glance... python client. So I write this code in openstack_utils for calling.
