Pants

Is there an easy way to run "reflection" python tests on pants metadata? I want to run some pants command like `pants list` and feed the result to a python test for processing

I've been thinking about (but haven't implemented), a plugin for reflection targets, like `pants_list(generated_file_name="./list.txt")` or `pants_peek(generated_file_name="peek.json")` that are "codegen" targets (generating the given file name) that can be consumed by tests etc.

Other than that, have the tests run outside a sandbox and internally invoke `pants --concurrent ...` might be a way to get the functionality working? not great though
