Introduce some plumbing which makes it possible to specify which ingress image to upgrade to for the upgrade test

**What this PR does / why we need it**:
Introduce a new flag which allows the user to run the ingress upgrade test with a specific image they are targeting for the upgrade. Before, it was only possible to run an upgrade test which upgraded to the latest image built from HEAD.
