This PR was squashed before being merged into the master branch.

Discussion
----------

Add a custom retry strategy to retry 404

### Problem
Sometimes, we get a webhook request and then we trying to ask the Github api for that issue, but the API says 404.

### Acknowledgement

I know I do more service definitions than needed, but I didnt want to pull in FrameworkBundle:5.2

### Excuse

The changes in src/Issues/GitHub/GitHubStatusApi.php is just CS.. I started to read/think there before I ended up with the RetryStrategy solution

### Shout out

@jderusse, this is really awesome =)
