The test is implemented as a go test. It can be executed as a bazel target. The general workflow is to setup a cluster, point the test to the workspace in which to find the kubeconfig and the constellation config and specify a target image, k8s and service version. The test will succeed if it detects all target versions in the cluster within the configured timeout. The CI automates the above steps. A separate workflow is introduced as there are multiple input fields to the test. Adding all of these to the manual e2e test seemed confusing. Co-authored-by: Fabian Kammel <fk@edgeless.systems>
