Description: See the request n° 10 in https://mojo.redhat.com/docs/DOC-1168581 for the proposed change.

Proposed change

• Usage of a new role (jq-tag-images in the "ansible-common" Git repo) to retrieve and tag the Docker images.
• Provide a flexible way (via a JSON structure) to describe the state of the images

This ties up with the latest issue that we had regarding the way the "pull-images.sh" script works in conjunction with the "docker-images-from-file" role.

We noticed that many images would simply use the "latest" tag in order to retrieve the latest available build. In some cases, this breaks the lab, which depends on a set of specific libraries to properly function (for example, rhel:7.5-404). 

This speaks to the practice of "loose tagging", which consists in retrieving the latest image every time the classroom is built.
