The link returned by service metrics is now built by looking up the deployment name in `report.Report` instead of assuming the service and the deployment have the same name.
The previous link to 'Monitor' contained a recording rule metric, and since not all Weave Clound instances have recording rules, the link would redirect to a 'Monitor' page without data points.
The recording rule metric has been substituted with the underlying query.
