Use in production & SNS

Verified to work using the Node.js 8.10 version runtime

mantle-lighthouse-lambda has been written to respond to SNS events. The file snsTrigger.js has been included as a way to allow http requests to publish SNS messages in a manor that the primary Lambda (mantle-lighthouse-lambda) can understand and use. In production, this function will need to reside as a separate Lambda function with access to the primary Lambda and the SNS Topic that the primary Lambda is subscribed to.

See the original lighthouse-lambda repo that this was based on for more info

## Full clean & dep refresh
docker run --rm -v "$PWD":/var/task lambci/lambda:build-nodejs8.10 bash -c "rm -f mantle-lighthouse-lambda.zip && rm -rf node_modules && npm install && zip mantle-lighthouse-lambda.zip -r node_modules index.js package.json"
