IncompatibleObjectVersion: Version 1.9 of Instance is not supported
【情景】为了启用metedata 功能，在compute节点上安装了nova-api-metadata，先是发现dashboard面板上的instance的操作状态无法更新，继而又发现
后台使用nova命令行也无法完成instance的创建、删除、开关机等操作。
【分析】因为nova相关模块部署的时间较早，版本较低，而新安装的模块nova-api-metadata版本较高，可能有不兼容的地方存在，比如api接口、对象属性等等，
所以导致nova api 调用操作无法生效，dashboard面板上的instance的操作状态无法更新。
【解决】修改以下文件：
1) /usr/lib/python2.7/dist-packages/nova/objects/base.py
2) /usr/lib/python2.7/dist-packages/nova/tests/objects/test_instance.py
3) /usr/lib/python2.7/dist-packages/nova/tests/objects/test_objects.py
