Subject: [PATCH] Add a test library

This adds empty __init__.py to tests so that a lib.py library of helper
functions can be imported from the tests.

Add captured_output to use with composer-cli tests to capture stdout/err
output from the functions.

(cherry picked from commit eeae331ba0af2609214fafbfad197c2b931e3675)
