When a project config is updated or a change is merged, all open changes on an entire project or branch need to be rechecked for mergeability. For projects or branches with lots of open changes, this can flood the queue with potentially slow checks. This will block simpler cases, such as checking mergeability of a single change during ReceiveCommits. Define a new Priority enum on the MergeabilityChecksExecutor so we can split the queue based on priority, allowing smaller, interactive changes such as pushes to not wait for the entire queued backlog.
