5a81a0661b Make DeschedulerStrategy.Params a pointer 
To avoid empty params fields when serializing:
  RemoveDuplicates:
    enabled: true
    params: {}
  RemovePodsHavingTooManyRestarts:
    enabled: true
    params:
      podsHavingTooManyRestarts: {}
  RemovePodsViolatingInterPodAntiAffinity:
    enabled: true
    params: {}
  RemovePodsViolatingNodeAffinity:
    enabled: true
    params:
      nodeAffinityType:
      - requiredDuringSchedulingIgnoredDuringExecution
  RemovePodsViolatingNodeTaints:
    enabled: true
    params: {}

c6ff87dbd6 Consider pod image in duplicates strategy 
This increases the specificity of the RemoveDuplicates strategy by
removing pods which not only have the same owner, but who also
must have the same list of container images. This also adds a
parameter, `ExcludeOwnerKinds` to the RemoveDuplicates strategy
which accepts a list of Kinds. If a pod has any of these Kinds as
an owner, that pod is not considered for eviction.

423ee35846 Add New PodLifeTime Strategy 
The new PodLifeTime descheduler strategy can be used to evict pods that
were created more than the configured number of seconds ago.

In the below example pods created more than 24 hours ago will be evicted.
````
apiVersion: "descheduler/v1alpha1"
kind: "DeschedulerPolicy"
strategies:
  "PodLifeTime":
     enabled: true
     params:
        maxPodLifeTimeSeconds: 86400

991eddb691 Turn StrategyParameters.NodeResourceUtilizationThresholds field into a pointer 
The field is intended to be omitempty when not set. Without a pointer the strategy
serialized into json string looks like:

```json
strategies:
  LowNodeUtilization:
    enabled: true
    params:
      nodeResourceUtilizationThresholds:
        numberOfNodes: 1
        targetThresholds:
          cpu: 50
          memory: 50
          pods: 20
        thresholds:
          cpu: 50
          memory: 50
          pods: 20
  RemoveDuplicates:
    enabled: true
    params:
      nodeResourceUtilizationThresholds: {}
  RemovePodsViolatingInterPodAntiAffinity:
    enabled: true
    params:
      nodeResourceUtilizationThresholds: {}
  RemovePodsViolatingNodeAffinity:
    enabled: true
    params:
      nodeAffinityType:
      - requiredDuringSchedulingIgnoredDuringExecution
      nodeResourceUtilizationThresholds: {}
  RemovePodsViolatingNodeTaints:
    enabled: true
    params:
      nodeResourceUtilizationThresholds: {}
```

It's preferred to have the following json string instead:
```
strategies:
  LowNodeUtilization:
    enabled: true
    params:
      nodeResourceUtilizationThresholds:
        numberOfNodes: 1
        targetThresholds:
          cpu: 50
          memory: 50
          pods: 20
        thresholds:
          cpu: 50
          memory: 50
          pods: 20
  RemoveDuplicates:
    enabled: true
  RemovePodsViolatingInterPodAntiAffinity:
    enabled: true
  RemovePodsViolatingNodeAffinity:
    enabled: true
    params:
      nodeAffinityType:
      - requiredDuringSchedulingIgnoredDuringExecution
  RemovePodsViolatingNodeTaints:
    enabled: true
```
