Create docker containerization scripts

This issue is for all of the work that needs to be done to move anything in the docker directory over from the old repo.

We need to move from the old repo:

/docker/db
/docker/flyway
/docker/pgadmin
/docker/ui
/docker/predicates-api and rename that dir to /docker/ratings-api
Then fix all of the scripts in docker directories to rename based on new directory names

What about /docker/caddy?
