Look into building a custom image with all our docker images built in
Similar to what CI/CD team is doing with their runners in https://dev.gitlab.org/cookbooks/packer-runner-machines/
Basically, we need to fetch all build images and create a custom GCP image that will be loaded automatically.
The goal of this is to see whether we can save on time (not to pull docker image every time a build needs to happen) and on money (no bandwidth will be used at every build to pull the docker image).
