Improvements as suggested by @risdenk:

- removed hostnames from `docker-compose.yml`
- removed unnecessary port definition
- changed container and/or service names where appropriate
- removed unnecessary `cat` command in ES Dockerfile
- removed `links` as `depends_on` already does that implicitly
- removed `command` from quepid definition in `docker-compose.yml`
