My problem is that I have several configuration settings that require
filenames, at various levels of nesting. I also kinda wanted to share
the cert files between all of the suites for the application.

It occurs that it might be possible to do something in a CT hook: it
could recursively look for string values and do $VAR replacements on
them from environment variables, or from that CT hook's options...

Sure, but these are explicitly test artifacts; I'm not going to be
keeping the production certificates and keys in the repository
(*those* get installed by, e.g., chef during machine bring-up).
