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.

6bde95c9a1 Use Structured Logging For Unknown Strategy Log Message 
Always use structured logging. Therefore update klog.Errorf() to instead
use klog.ErrorS().

Here is an example of the new log message.
