Stand up a basic API

[cdmgtri]

While work is being done on the database design and CMF...

• [x] Stand up and deploy a basic API that connects to a Postgres database and runs in Docker containers.
• [ ] Leverage applicable CIS Benchmark libraries for Docker, Postgres, TomCat, etc.
• [x] Implement a simple test call that returns a value from the database

Created a docker-compose setup. There are two docker containers; one for the API controller and underlying models, and another docker container for a postgresql database.

The API now is now wired up to the Postgres database.
