Env variables for DB no longer work.

[JakeDEvans]

I'm not sure which version, but I can no longer use these env vars to create the database on v6.18 or v7.2.3

    environment:
     - DB_TYPE=postgresql
     - DB_USER=artifactory
     - DB_PASSWORD=password

instead I must manually update the system.yml file, which is then rewritten with an encrypted password.

This also makes changing postgres passwords unlikely.

@JakeDEvans First of all this repo is deprecated, we recommend to use wiki for the latest compose.

1. On the database creation - the new compose has this:

   postgres:
   image: ${DOCKER_REGISTRY}/postgres:9.6.11
   container_name: postgresql
   environment:
    - POSTGRES_DB=artifactory
    - POSTGRES_USER=artifactory
    - POSTGRES_PASSWORD=password

   which creates the required user and password in the database.

2. The same can be passed to artifactory to use these creds via system.yaml or by running config.sh, the interactive script to set the system.yaml.

Let me know if this is not making sense.

The docker compose including postgres is in the templates folder of the package.
