150f945592 lownodeutilization: clasify pods of over utilized nodes only 
Only over utilized nodes need clasification of pods into categories.
Thus, skipping categorizing of pods which saves computation time in cases
where the number of over utilized nodes makes less than 50% of all nodes
or their fraction.

e3d06d1541 Create k8s event when a pod is successfully evicted 
This allows end users to more easily monitor when the descheduler evicts
a pod in their environment. Prior to adding k8s event support the only
way to track evicted pods was to view the logs.

9ea6aa536e Update CriticalPod unit test 
The kubelet used to only determine critical pods by the namespace and an annotation (see [1], where our code switched from only checking the annotation to using the kubelet package helper, which at that revision also only checked for an annotation and namespace). However, now the kubelet uses Pod Priority to check for critical pods[3], which is controlled by an admission plugin[4]. Given that testing the functioning of the admission plugin is out of the scope of this repository, it is probably sufficient to manually set the pod priority to critical, to ensure that our Descheduler code behaves properly in response.

dc7f9efc19 Descheduler can evict all types of pods with special annotation 
When pod has this annotation, descheduler will always try to evict this pod.
User can control which pods (only pods with this annotation) will be evicted.
