6e953b2ff3 Separate migration of strategy configuration from the constructing and running the plugins (#999)
* Remove log level from Errors

Every error printed via Errors is expected to be important and always
printable.

* Invoke first Deschedule and then Balance extension points (breaking change)

* Separate plugin arg conversion from pluginsMap

* Seperate profile population from plugin execution

* Convert strategy params into profiles outside the main descheduling loop

Strategy params are static and do not change in time.

* Bump the internal DeschedulerPolicy to v1alpha2

Drop conversion from v1alpha1 to internal

* add tests to v1alpha1 to internal conversion

* add tests to strategyParamsToPluginArgs params wiring

* in v1alpha1 evictableNamespaces are still Namespaces

* add test passing in all params

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.

1529180d70 feat: support eviction of failed bare pods
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.

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
```
