ac3362149b Add RemovePodsViolatingNodeTaints taint exclusion 
Add taint exclusion to RemovePodsViolatingNodeTaints. This permits node
taints to be ignored by allowing users to specify ignored taint keys or
ignored taint key=value pairs.

203388ff1a Evictor: report successful eviction independently of the dry-mode

e0f086ff85 Use a fake client when evicting pods by individual strategies to accumulate the evictions 
Currently, when the descheduler is running with the --dry-run on, no strategy actually
evicts a pod so every strategy always starts with a complete list of
pods. E.g. when the PodLifeTime strategy evicts few pods, the RemoveDuplicatePods
strategy still takes into account even the pods eliminated by the PodLifeTime
strategy. Which does not correspond to the real case scenarios as the
same pod can be evicted multiple times. Instead, use a fake client and
evict/delete the pods from its cache so the strategies evict each pod
at most once as it would be normally done in a real cluster.

This patch adds the policy(evictFailedBarePods) to allow the failed
pods without ownerReferences to be evicted. For backward compatibility,
disable the policy by default. Address #644.

RemoveDuplicates: take node taints, node affinity and node selector into account when computing a number of feasible nodes for the average occurence of pods per node

5396282e3d RemoveDuplicates: take node taints, node affinity and node selector into account when computing a number of feasible nodes for the average occurence of pods per node 
Nodes with taints which are not tolerated by evicted pods will never run the
pods. The same holds for node affinity and node selector.
So increase the number of pods per feasible nodes to decrease the
number of evicted pods.
