Serverless file upload setup with Claudia + Node

1. route for user location json file upload
2. internal api for getting all locations
3. internal api for getting location details

build steps

configure AWS and get necessary authorizations

• general overview: https://github.com/claudiajs/claudia-api-builder/blob/master/docs/authorization.md
• I used AWS cli and passed in key/secret directly, but many options
• authentication in this version is AWS_IAM, permissions are summarized here: https://docs.aws.amazon.com/apigateway/latest/developerguide/permissions.html
