This directory is currently a fixed location to make troubleshooting easier.
It is cleared before each test target runs, but is preserved when a test target finishes.
This allows the contents to be inspected when a test fails.
The previous location was `~/ansible_testing/`.
The new location is within the content root:
- `test/results/.tmp/output_dir` for Ansible
- `tests/output/.tmp/output_dir` for Ansible Collections
Moving the directory reduces the number of places on the filesystem where tests create output.
It also enables the results to be returned from delegated systems.
