Setup infrastructure meant for the user-posts-lambda repo.

Manages stacks for API Gateway, Cognito, DynamoDB and the Lambda function.

Notes:

• all routes are secured with an API key that is generated in the API Gateway
• posts routes are also secured with a Cognito-based authorizer

A Postman collection is included for easier testing.

Since it's a CDK project, the standard commands apply:

• mvn package compile and run tests
• cdk ls list all stacks in the app
• cdk synth emits the synthesized CloudFormation template
• cdk deploy deploy this stack to your default AWS account/region
• cdk diff compare deployed stack with current state
• cdk docs open CDK documentation

You should run cdk bootstrap if this is your first CDK project.
