Docker Container: Init 1 & Initialisation

- Now using a setup script before starting the app. The separation of
the run script and the setup script will make service initialisation a
little bit clearer
- Now calling start.sh script as ENTRYPOINT and S6 as CMD. This way
when running the container with just a shell script, the start.sh
script will be launched before, making debugging easier
- Added note about `.dockerignore` ignored during Docker Hub Automated
Build

- **Domain**: fill in with Docker container IP(e.g. `192.168.99.100`). But if you want to access your Gogs instance from a different physical machine, please fill in with the hostname or IP address of the Docker host machine.
- **SSH Port**: Use the exposed port from Docker container. For example, your SSH server listens on `22` inside Docker, but you expose it by `10022:22`, then use `10022` for this value.
- **HTTP Port**: Use port you want Gogs to listen on inside Docker container. For example, your Gogs listens on `3000` inside Docker, and you expose it by `10080:3000`, but you still use `3000` for this value.
- **Application URL**: Use combination of **Domain** and **exposed HTTP Port** values(e.g. `http://192.168.99.100:10080/`).

- `docker pull gogs/gogs`
- `docker stop gogs`
- `docker rm gogs`
- Finally, create container as the first time and don't forget to do same volume and port mapping.
- Finally, create container as the first time and don't forget to do same volume and port mapping.
## Known Issues
- [Use ctrl+c when clone through SSH makes Docker exit unexpectedly](https://github.com/gogits/gogs/issues/1499)
- `.dockerignore` seems to be ignored during Docker Hub Automated build
