On GitHub we cannot reliably update all information that's needed for doing a canmerge check using events. Namely completely missing events on branch protection changes and ambiguous status events that might match several changes due to its data model to have statuses on the commit instead the pr. This was no problem in the past since this information was only used during the enqueue phase which is directly after the event preprocessing phase. However with circular dependencies we re-do the can merge check just before merging again and need to act on recent data. Therefore add an allow_refresh flag that makes it possible to refresh the volatile parts of the data we don't get events for. This is only used on GitHub for now as the other drivers are either correctly updating their states using events or didn't yet optimize to not do api calls within the main loop yet (pagure).
