/users API for AWS - Task 248

[lbrown51]

Resolves #248

• This is code that can be uploaded to aws lambda and contains the functionality of the /users api
  • The lambda function is HttpTriggerAPIUsers
• To use, you can make calls to https://mchfd7t6l4.execute-api.us-west-2.amazonaws.com/users
• It accepts two different methods
  • GET, which takes no parameters
  • and POST, which takes {"firstName": first_name, "lastName": last_name, "email": email}
• It makes use of the API Gateway nsc-api-dev-usw2-thursday
  • All of the apis can and should be under this API Gateway.
  • I created mine as /users - ANY which means it takes any HTTP request to /users and handles it. This is also basically how the Azure api works, so I think it makes sense.
• I don't know that it can be tested locally, but you can certainly test it using Postman
• The environment variables are in the configuration settings for the function!
