Consolidate docker-compose.yml file #87
Description
We're consolidating our docker-compose file for the conserver. I.e. We will:
- provide an open source (committed to github) example_docker-compose.yml file
- Add docker-compose.yml to .gitignore since it is intended to be customized for each deployment
- Remove our docker-compose-override.yml file (copying over all our own overridden setting to the docker-compose.yml file) since it will no longer be needed
