* Wiped out a ton of warnings about comments. * Created consts for `MetricType` values. * `externalInfoMap` can now track multiple series with the same name/namespace and different labels. * `namespace` parameter of external metrics queries is now respected (albeit very rudimentarily) * Metric converter values for external metrics are now converted the same way as for custom metrics (probably still some opportunity for consolidation). * Lots of TODOs actually done. * Deleted a lot of commented out code.
