feat: Add separate config for demo setup, tweak docs

This PR adds `config-demo.toml` to `Dockerfile` which uses the db host
`demo-db`. This is more suited for demo setups. For normal docker installations
the db host is changed back to `db` which is a better sane default.
Reworded `INSTALL.md` and `README.md` for more clarity on docker
installation and configuration.

 You can checkout the [docker-compose.yml](docker-compose.yml) to get an idea of how to run `listmonk` with `PostgreSQL` together using Docker.

-- `docker-compose run --rm app ./listmonk --install` to setup the DB.
+- **Run the services**: `docker-compose up -d app db` to run all the services together. If this is a first time setup, you will see some errors related to DB which occur because migrations haven't been applied yet. Don't worry, follow the next step.
+- **Apply DB migrations**: `docker-compose run --rm app ./listmonk --install`.
+-  Ensure that both the containers are in running state before proceeding. If the app container is not `up`, you might need to restart the app container once: `docker-compose restart app`.

+### Mounting a custom config file
+
+You are expected to tweak [config.toml.sample](config.toml.sample) for actual use with your custom settings. To mount the `config.toml` file,
+you can add the following section to `docker-compose.yml`:
+
+```
+  app:
+    <<: *app-defaults
+    depends_on:
+      - db
+    volume:
+    - ./path/on/host/config.toml/:/listmonk/config.toml
+```
+
+This will `mount` your local `config.toml` inside the container at `listmonk/config.toml`.
+
 _NOTE_: This `docker-compose` file works with Docker Engine 18.06.0+ and `docker-compose` which supports file format 3.7.
