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.

a490726245 Validate resource names to pass to thresholds 
This commit adds checks to only allow valid resource names for the
thresholds field, which are "cpu", "memory", and "pods" right now.

For the other valid or invalid resource names, descheduler will now
throw an error.

Also, tests have been added to test the added behavior.

d54b73a6ba Add log messages for target, underutilized nodes 
This commit adds log messages to be printed whenever a node is
identified as a target node from which the pods can be evicted or
as an underutilized node to which the evicted pods can be
scheduled, if at all.

This should help with debugging as well as with letting the user
know the identified nodes.
