This should be useful both for ResourceGroup, which does unspeakable things
to its member definitions in order to substitute in resource names, and for
distributing members across availability zones.

Previously we always used a random short_id, and that is indeed what we
want for Autoscaling groups, but ResourceGroups generally use sequential
IDs, so pass a function that generates them instead of hard-coding it.
By happy accident, this makes the tests a bit nicer too.

The naming in this function dates from an earlier era, before we had the
ResourceDefinition class. This modifies the function name from
resource_templates() to member_definitions() and also modifies the
parameter/variable names to make their meanings clearer. The documentation
is also improved with a more thorough description of what the function
does.

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.
