Keystone domain for Heat

Keystone domain for Heat

This patch adds support for configuring Keystone domain for Heat
via heat-keystone-setup-domain script. It should be reverted
as soon as Keystone v3 is fully functional.

This patch won't be fully functional without either python-keystoneclient
fix [1] or workaround [2].
