// For example, in a test named `a/to_b/from_cluster-0`,
// `a` is the source deployment, `b` is the destination deployment and
// `cluster-0` marks which instance of the source deployment.
//
// We use a combination of deployment name and cluster name to identify
// a particular source instance, as there should typically be one instance
