Local Development Suite - DynamoDB

[rgraue]

Swapping to Dynamo opens up a lot of opportunities in the cloud, but closes some doors locally. A nice to have is a local dynamo instance to hit locally.

Needs to:

• standup local (mock) dynamo instance using docker-compose
• be able to simulate full E2E usage

Technical Notes:

• Needs to specify which dynamo instance to hit using .env files. ie .env.LOCAL & .env.PROD
• .env.PROD can probably be made during pipeline?
• Try using https://docs.localstack.cloud/user-guide/aws/dynamodb/
• simple set of mock data checked-in to help on db init
