create schema in container automatically

[jenhagg]

Purpose

Simplify local integration tests by automating schema creation in local db.

What it does

Add schema.sql to git, and mount it in the local db container. Postgres will automatically run the scripts in /docker-entrypoint-initdb.d which eliminates the need to any manual db management in this case.

To test this, I removed the existing containers (docker-compose -f stack.yml down and docker container prune) then recreated them and logged in using psql to verify.

@kasparm and @BainanXia, can look at this PR? I think you have already everything set up on your machine or the server. This should be not much work to checkout the branch and run the test.

All tests passed. Tables for testing purpose are created automatically once the the container is up. Thanks.

[kasparm]

tests passed!
