openstack image list: error: unrecognized arguments: --property status=active

devstack安装OpenStack时候报错如下：

11870 2015-05-27 07:24:58.982 | usage: openstack image list [-h] [-f {csv,html,json,table,yaml}] [-c COLUMN]

这主要是由于python-openstackclient的版本太低导致的，openstack image list命令执行的时候不识别参数--property，只要升级即可解决。

sudo pip install python-openstackclient --upgrade
