Add GH labels for build-success/failure


When trying to sort PRs it would be helpful to filter passing/failing PRs. If Circle could add a label when a build fails/passes it would be really helpful.


You can automate this yourself by posting to the github api.


Expanding on this:

Add your github access token to your build enviroment, then use curl to speak to github. you can find the pr url as part of the build job.
