bottlenecks openstack Newton support
JIRA: BOTTLENECK-119 Change the file of template.py manager.py and common.py file This change helps Bottlenecks project support Newton. template.py support stack operation. manager.py support nova and glance operation. common.py support some operations of openstack Newton.
