+    Find libc++ JobMetric entries and create aggregate metrics for them.
+
+    Sort the libc++ JobMetric entries by workflow id, and for each workflow
+    id group them by stages.  Create an aggreate metric for each stage for each
+    unique workflow id.  Append each aggregate metric to the workflow_metrics

+    How aggreates are computed:
+    queue time: Time from when first job in group is created until last job in
+                group has started.
+    run time: Time from when first job in group starts running until last job
+              in group finishes running.
+    status: logical 'or' of all the job statuses in the group.
