heat_template_version needed in Network templates

[Steve McLellan]

Without heat_template_version heat assumes CFN format templates. Post Icehouse, HOT has added a lot of functionality not in CFN, and template version appears to be mandatory in recent builds of heat - without it, heat raises a 400 error: "The template version is invalid: Template version was not provided" when creating networks.

    Add heat_template_version to network fragments

    Without heat_template_version heat assumes CFN format templates.
    Post Icehouse, HOT has added a lot of functionality not in CFN, and
    template version appears to be mandatory in recent builds of heat -
    without it, heat raises a 400 error: "The template version is invalid:
    Template version was not provided".

    This patch changes engine/heat_stack to add heat_template_version
    if it's not already present in a template at push time, and to reject
    heat_template_version if it's in a dictionary passed to updateTemplate
    that does not match the expected version.
