Add support for OpenSrack Newton

JIRA: YARDSTICK-410

This patch uses keystoneauth1.session to initialize the client for Heat
The keystoneauth1.session.Session class was introduced into keystoneauth1
as an attempt to bring a unified interface to the various OpenStack clients
that share common authentication and request parameters between a variety of
services.
