This patch contains a set of changes needed to add WEBEXT telemetry probes keyed by addon id. The telemetry probes keyed by addon id has been added as separate telemetry histograms named after the related generic WEBEXT probe with the additional "_BY_ADDONID" suffix. A set of small helper methods have been defined in a new ExtensionTelemetry object, exported by the ExtensionUtils.jsm.
