Github status for building PRs

[thedrow]

We're using hydra as the CI system for RethinkDB and we'd like to get a status for each PR we have.
I know we can use any Github client for this and include it in the scripts but it'd be nice to have it out of the box.

It's already possible: https://github.com/input-output-hk/iohk-nixops/blob/master/modules/hydra-master.nix#L53-L56

I don't see any documentation for it though. How do I activate it?
