fix network value for stats summary for multiple network interfaces
This PR is part of [Heapster #1788](https://github.com/kubernetes/heapster/pull/1788).
The original reason is when there are more than one none `lo`, `docker0`, `veth` network interfaces instead of just one `eth0`, the network interface value is only partial and does not correct. For now, summary stats api only gets the eth0 network interface values.
The original issues about this can be find in [Heapster #1058](https://github.com/kubernetes/heapster/issues/1058) and [Cadvisor #1593](https://github.com/google/cadvisor/issues/1593).

Add PodDisruptionBudget support in pod preemption
**What this PR does / why we need it**:

change DefaultGarbageCollectionPolicy to DeleteDependents for workloads controllers
**What this PR does / why we need it**:
As part of the apps/v1 GA effort (kubernetes/features#353) for v1.9. For core controllers, like `Deployment`, `DaemonSet`, `ReplicaSet`, and `StatefulSet`, changing the `DefaultGarbageCollectionPolicy` from `OrphanDependents` to `DeleteDependents` will make these objects consistent with the default behavior for all new objects.
For legacy API versions, the `DefaultGarbageCollectionPolicy` remains `OrphanDependents`.

**Release note**:
```release-note
The default garbage collection policy for Deployment, DaemonSet, StatefulSet, and ReplicaSet has changed from OrphanDependents to DeleteDependents when the deletion is requested through an `apps/v1` endpoint. Clients using older endpoints will be unaffected. This change is only at the REST API level and is independent of the default behavior of particular clients (e.g. this does not affect the default for the kubectl `--cascade` flag).
If you upgrade your client-go libs and use the `AppsV1()` interface, please note that the default garbage collection behavior is changed.

**Special notes for your reviewer**:
We wanted to use this test pkg while creating a new integration test fixture, the idea of starting the api-server without actually starting a proper etcd (integration etcd ) is very useful, if would be great to extend this for other usecases such as `insecure` mode too.
It will also be useful to get the working `tmpdir` returned so that we could store additional certs (such as service account public and private keys and kubeconf for this apiserver) if needed, which will be cleaned up automatically by the `teardownFn` when the api server is terminating.

Action required for existing users of the LocalPersistentVolumes alpha feature:
* The VolumeScheduling feature gate also has to be enabled on kube-scheduler and kube-controller-manager.
* The NoVolumeNodeConflict predicate has been removed. For non-default schedulers, update your scheduler policy.
* The CheckVolumeBinding predicate has to be enabled in non-default schedulers.

Kubelet flags take precedence over config from files/ConfigMaps
Changes the Kubelet configuration flag precedence order so that flags
take precedence over config from files/ConfigMaps.
See:
https://docs.google.com/document/d/18-MsChpTkrMGCSqAQN9QGgWuuFoK90SznBbwVkfZryo/
Also modifies e2e node test suite to transform all relevant Kubelet flags into
a config file before starting tests when the KubeletConfigFile feature gate is
true, and turns on the KubeletConfigFile gate for all e2e node tests.
This allows the alpha dynamic Kubelet config feature to continue to
work in tests after the precedence change.

Related: https://github.com/kubernetes/features/issues/281
```release-note
CLI flags passed to the Kubelet now take precedence over Kubelet config files and dynamic Kubelet config. This helps ensure backwards compatible behavior across Kubelet binary updates.

Add support to take nominated pods into account during scheduling to avoid starvation of higher priority pods
**What this PR does / why we need it**:
When a pod preempts lower priority pods, the preemptor gets a "nominated node name" annotation. We call such a pod a nominated pod. This PR adds the logic to take such nominated pods into account when scheduling other pods on the same node that the nominated pod is expected to run. This is needed to avoid starvation of preemptor pods. Otherwise, lower priority pods may fill up the space freed after preemption before the preemptor gets a chance to get scheduled.

Take disk requests into account during evictions
fixes#54314
This PR is part of the local storage feature, and it makes the eviction manager take disk requests into account during disk evictions.
This uses the same eviction strategy as we do for memory.
Disk requests are only considered when the LocalStorageCapacityIsolation feature gate is enabled. This is enforced by adding a check for the feature gate in getRequests().
I have added unit testing to ensure that previous behavior is preserved when the feature gate is disabled.
Most of the changes are testing. Reviewers should focus on changes in **eviction/helpers.go**
