Fixed: * `basicMetricLister` wasn't applying the appropriate start time because I had forgotten to set the `lookback`. There are still a number of issues: * The `externalPrometheusProvider` is not hooked up to the web application yet, so it doesn't serve requests. * The namespace and label approach used in `external_info_map.go` is horrifically incorrect. It doesn't appropriately store multiple series with the same name but different labels. * The configuration is still not updated to appropriately handle external metrics, it's sort of half-piggy-backing on the pre-existing work.
