      Description of problem:

      See https://github.com/xpivarc/kubevirt/tree/priorityqueue-bug
The problem is that we use simple "queue.Add" when an even occurs from informer. This will make the item to jump the queue. 
In extreme cases it was observed that active migrations will not get to be processed within 5 minutes and so the launcher timeout, leading to migration deadlock.
