Subject: [PATCH] ci: k8s: Add a method to install CRI-O
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This is based on official CRI-O documentations[0] and right now we're
making this specific to Ubuntu as that's what we have as runners.

We may want to expand this in the future, but we're good for now.
