Wraps the parts of the notification API that allows the user to mark notifications as read.
New methods are :
- Notification.mark_as_read : marks a single notification thread as read
- Repository.mark_notifications_as_read : marks all the notifications for a given repository as read
- AuthenticatedUser.mark_notifications_as_read : marks all the notifications as read
Aims to fix : https://github.com/PyGithub/PyGithub/issues/571 and simply uses the APIs described on this page : https://developer.github.com/enterprise/11.10.340/v3/activity/notifications/
A weird thing I noticed doing this is that Repository.notifications_url doesn't seem to be usable directly. I used Repository.url + "/notifications" instead.
