Copy subdirectories and their contents in to the tmpdir.

We've started breaking things like json polcies and templates
out of the raw .tf files in to subdirectories. This ensures those are copied over too.

dir here is resources or resources/<env> so this is working with an expected structure where the templates and files are inside resources rather than in <project>. Is that correct as it doesn't match up with @surminus's comment on #46?

[gpeng]

This works for a directory structure as per @surminus's #46 comment if we also pass the project directory into the loop at line line 163

Sorry, seem to have left this go stale. I believe this approach is correct and the one I stated here is incorrect as we might want to have different files or templates with a different environment, which this loop takes account of.

👍 merge!

This doesn't actually work so I am going to close it off. The problem is that we "flatten" everything into a single temporary directory (foo) and then copy templates and files into subdirectories beneath then (foo/templates). When we run the rake task the code references the relative directory (templates/file.json) but Terraform only works on a CWD basis, so can't find the file.

I have suggested an alternative in a143e95.
