When we moved parameters from the stack table to the template table
we did it in a "flexible" way, but this led to some difficult to
diagnose problems. So this patch totally removes "env" as an argument
to the Stack class to make absolutely sure that we are doing this
correctly. I came across these bugs when rebasing decouple-nested.
- env was not getting passed into instance group make_templates()
- template deepcopy was not working correctly (causing some problems
when deleting backup stacks)

Instead of building nested templates for Autoscaling manually, use the
Template.add_resource() method to build them up programmatically.

This introduces a new package for autoscaling code which is
intended for use outside of the Heat engine, and moves the
resource_templates function into a new module, heat.scaling.template.
The function hasn't been changed at all.
