Inconsistency between design summary and TODO in Component Implementation 2

[markmccrum]

The design summary states that the number of LED transitions is to be reported as telemetry. In the code excerpt for Led::run_handler there is a TODO suggesting that an event should be used instead.

                // TODO: Add an event to report the number of LED transitions (this->transitions)

It probably makes more sense for it to be telemetry.
