742539 - Make persistent telemetry more useful

Status: RESOLVED WORKSFORME

(Toolkit :: Telemetry, defect)

Description

[(dormant account)]

Currently persistent telemetry fails to report useful data. This is best illustrated by the following:
456     if (havePreviousSession) {
457       payloadObj.histograms = previousHistograms;
458     }
459     else {
460       payloadObj.simpleMeasurements = getSimpleMeasurements();
461       payloadObj.histograms = this.getHistograms(Telemetry.histogramSnapshots);
462       payloadObj.slowSQL = Telemetry.slowSQL;
463       payloadObj.chromeHangs = Telemetry.chromeHangs;
464       payloadObj.addonHistograms = this.getAddonHistograms();
465     }

Additionally telemetry data is only saved on shutdown. This means we miss about 10% of our persistent reports where browser doesn't shutdown successfully(according to SHUTDOWN_OK)

s/useful data/some useful data/. Persistent telemetry is very useful already :)
