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: {}

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.

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

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
```
