Mike Dame f5e9f07321 Move kind setup to e2e script 
This moves the kind setup (previously used by Travis) to the e2e runner script
to accomodate the switch to Prow. This provides a KIND_E2E env var to specify
whether to run the tests in kind, or (by default) to run locally).

Mike Dame f5e4acdd8a Make evictLocalStoragePods a property of PodEvictor 
This is a minor refactor of PodEvictor to include evictLocalStoragePods as a
property (so that it doesn't need to be passed to each strategy function.) It
also removes ListEvictablePodsOnNode and extends ListPodsOnANode with an optional
"filter" function parameter, so that for example IsEvictable can be passed to it
and achieve the same results as the function formerly known as ListEvictablePodsOnNode.
This approach also now allows strategies to more explicitly extend their criteria of what
IsEvictable considers an evictable pod (such as NodeAffinity, which checks that the pod
can fit on any other node).

Jan Chaloupka 5a81a0661b Make DeschedulerStrategy.Params a pointer

    params:
      podsHavingTooManyRestarts: {}
  RemovePodsViolatingInterPodAntiAffinity:
    enabled: true
    params: {}
  RemovePodsViolatingNodeAffinity:
    enabled: true
    params:
      nodeAffinityType:
      - requiredDuringSchedulingIgnoredDuringExecution
  RemovePodsViolatingNodeTaints:
    enabled: true
    params: {}

Jan Chaloupka 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
```
