Using Pull Dog

[ffMathy]

I recently launched a service that I believe could be helpful in this repository. It's free to use (from a demo-cluster pool of free servers), and I need feedback. I think it could really be a win-win for us both.

https://github.com/apps/pull-dog

It automatically spawns up a Docker-based test environment for each of your pull requests, based on a docker-compose.yml file that you choose.

I think it could be helpful in general, to test things out in production before they are merged.

What do you think?
