Serverless Slackbot Part 1: Define the Serverless configuration

Part 1 of building a “Serverless” Slackbot is to define the serverless configuration.

I will build on this and share more of the actual lambda and how to handle a nested request and eventually build a simple slackbot that executes this function.

A simple serverless.yml definition to define a Lambda function and pull API_KEY and API_SECRET from SSM Parameter Store, so you can safely manage the secret sauce.
