Subject: [PATCH] Update Dockerfile to utilize Docker Cloud auto build

* Use the repository as context, instead of released .tar.gz
* Remove version information from Dockerfile, and let Docker Cloud handle it
* Add .dockerignore

Next steps:

1. Connect repository in Docker Cloud
2. Setup automated builds:
   - A push on `master` branch triggers build for `unstable` tag
   - A tag matching /^v[0-9]+(\.[0-9]+){2}$/ triggers build for a same-named tag

Refer to #1914
