We need a bulletproof-workflow to test things on K3s.

• The cluster would be setup once for a pipeline, there should be Python + Go + Kuttl installed (both if specified in input parameter + version as parameters) and there should be a make test command invoked (also possible to parametrize)
• The cluster setup should wait until the cluster is fully set-up (all pods are ready - including metrics-server)
• There should be a image load step that would allow to perform a "docker load" from a tar.gz produced by other pipeline step, so the image could be tested BEFORE PUBLISHING
• There should be a stage to install given helm chart with specified values path, that would wait for installation to be completed
