Run the Backstroke project on your local system

[1egoman]

As of writing this, I think I'm the only one who has actually run the entire Backstroke stack locally. I'd love for other people to try it out and confirm that I haven't made any mistakes documenting the process.

Here's a walkthrough on how to set up the system: https://github.com/backstrokeapp/deployment/blob/master/README.md#deployment. In particular, I'm looking for feedback related to the setup process with docker-compose, but I'd love to hear any thoughts you have in general. My goal is to make this process as easy as possible for new contributors.

Once you're done, feel free to add your name to the hall of fame with a pull request! Thanks for helping out with Backstroke!
