Google MQTT MKR1000 example

I can not get the MKR1000 to connect to Google IoT Core. I am still working on it, but here is a description of my attempt and results.

A couple of questions:

1. Which domains need to be specified in the firmware/certificate utility for add domains?
2. Does it matter what domains are loaded above for when you use the sketch to generate the microchip crypto PEM key? I'm assuming we use the tools/utility sketch with JWS in name since the MQTT MKR1000 code in this repo is a JWT sample?
3. Does it matter which slot we use when we store the key using the above utility?

I finally got this working. This sample works with the crypto chip and the gcp example works doing it in software. The github repot I linked above has my work to get it done.
