Adds product numbers, fahrenheit, and 2nd gen temp sensor

Updates

• Product numbers: All devices now have a new product number field. This product number is the same product number that can be found on the support pages for both Sensors and Cloud Connectors. Product numbers can be used to sort and filter devices when calling getAllDevices. They can also be used as a filter when starting a new event stream by calling subscribeToDevices.
• Fahrenheit support: In addition to celsius field on temperature events, there is now also a fahrenheit field. Fahrenheit can also be used to create a new temperature event to publish to a device emulator.
• 2nd gen temperature sensor: The new 2nd generation temperature sensor from Disruptive Technologies supports sampling additional temperature samples between two heartbeats. These samples are available as a new samples array on a TemperatureEvent.
