Stack refactor (#38)

* Refactored openstack-stack role to:

- Convert static heat template files to ansible templates
- Include native ansible groups via openstack metadata. This removes the need for a playbook to map host groups
- Some code cleanup

* Deleting commentd out code and irrelevant plays

* Refactored openstack-stack role to:

- Convert static heat template files to ansible templates
- Include native ansible groups via openstack metadata. This removes the need for a playbook to map host groups
- Some code cleanup

* Deleting commentd out code and irrelevant plays

* Replacing stack parameters with jinja expressions

* Updating sample inventory to work with latest dynamic inventory changes

* updating inventory with host group mapping. making sync keys optional

* Missing cluster_hosts group

* Updating to add infra_hosts

* Updating inventory per comments from oybed and sabre1041
