Add integration for new bors

[Kobzol]

I think that the best way to test the new bors implementation is to start using it in the wild. This PR integrates this repo with the bot (some more integration has to be done externally through GitHub). For now, I would suggest to integrate it e.g. under the @borsnew name, and start testing its try build functionality. The bot cannot do merges or approvals yet, and it doesn't touch master in any way, so hopefully it shouldn't cause any troubles for this repo.

Happy to merge this -- I guess we'll need to figure out credentials if we want try builds to actually work.
