AIAP - Extract logs from runner container

This adds a new script to the runner container that is run in the
entrypoint which runs the log gathering ansible playbook from
inside the runner container. The gate then extracts these logs
with a new role.

This also updates the image_build script to fix how it changes
the container imagePullPolicy

Closes: #658
Relates-To: #659
