Martin Atkins 1dece66b10 instances: A package for module/resource reptition
This package aims to encapsulate the module/resource repetition problem
so that Terraform Core's graph node DynamicExpand implementations can be
simpler.

This is also a building block on the path towards module repetition, by
modelling the recursive expansion of modules and their contents. This will
allow the Terraform Core plan graph to have one node per configuration
construct, each of which will DynamicExpand into as many sub-nodes as
necessary to cover all of the recursive module instantiations.

For the moment this is just dead code, because Terraform Core isn't yet
updated to use it.
