[Local] Create a Dockerfile to build an image and run

### Description
We just need to create an simple docker container enough to run the app. Should include those 2 steps
1) Set up a `host.docker.internal` so that the container can call to local mongo db (for local env) https://stackoverflow.com/questions/43800164/connecting-to-local-mongodb-from-docker-container
2) Running `./gradlew build` to create a jar file
3) Create Dockerfile for spring app https://spring.io/guides/gs/spring-boot-docker/
4) build and update to registry
