A daemon node that sets up a connection to the AWS IoT service.
Setup in AWS IoT Cloud
It needs a device (thing) set up in the AWS cloud per the instructions here: AWS IOT Getting Started
Proper certificates need to be generate and attached to the Thing and policies set up so that this node can access the Thing Shadow using the certs and private key.
The cert, private key and CA cert needs to be downloaded from AWS and placed somewhere in the local file system where the Elixir runtime can access it.
Configure these locations in the application config file.
