This wires up together both the Telemetry command line and runner, responsible
of running stories and collecting artifacts (traces, logs, etc.), together with
the results_processor, responsible of processing such artifacts and e.g. run
metrics to produce various kinds of outputs (histograms, csv, results.html).
