Fix Stackdriver Logging e2e tests
This PR fixes the problems in the SD Logging tests:
- Because of Docker problem, trimming works unpredictably on some OSs, so instead of assuming exact trimming mechanism, just assume trimming
- Increases the throughput of reading logs through Pub/Sub by increasing the parallelism level

e2e_node: small fixes to setup_host.sh for Ubuntu Trusty
**What this PR does / why we need it**:
Two small fixes for how nsenter is built from source and installed on Ubuntu Trusty:
1. Use mktemp for the creating the build directory instead of a hard coded name
2. Use current (2.31) util-linux instead of 3+ year old version
**Which issue(s) this PR fixes**:
Fixes#56106
**Special notes for your reviewer**:
See https://github.com/kubernetes/kubernetes/issues/56106 for some thoughts on other ways to address this. My patch for util-linux 2.31 may just be a band-aid?

Use k8s.gcr.io vanity domain for container images
Related issue: https://github.com/kubernetes/release/issues/281
```release-note
Use "k8s.gcr.io" for container images rather than "gcr.io/google_containers". This is just a redirect, for now, so should not impact anyone materially.
Documentation and tools should all convert to the new name. Users should take note of this in case they see this new name in the system.
```
The e2e_node test environment setup script is hard coded to pull down a
quite old version of util-linux in order to build nsenter on trusty,
which sadly is well known to not include an nsenter executable.
While "just a test", it's unfortunate to be building from really old
util-linux sources when newer are available.
Signed-off-by: Tim Pepper <tpepper@vmware.com>
There's a bit of a hack in place to insure nsenter is present on Ubuntu
trusty, which doesn't otherwise include it. This downloads util-linux
to a hard coded directory in /tmp which is a bad practice. Even though
"this is just a test case" it should properly use mktemp.

Add brackets around IPv6 addrs in e2e test IP:port endpoints
There are several locations in the e2e tests where endpoints of the
form IPv6:port use IPv6 addresses directly, without surrounding brackets.
Brackets are required around IPv6 addresses in this case, in order to
distinguish the colons in the IPv6 address from the colon immediately
preceding the port.
Also, wherever the curl command might be used with an IPv6 address
surrounded in brackets, the "-g" argument is added to the curl
command line arguments so that the brackets can be interpreted
correctly.
fixes#52746
**What this PR does / why we need it**:
This PR adds brackets around IPv6 addresses when they appear as part of an IPv6-addr:port endpoint
in the e2e tests. This is needed because any connections that attempt to use IPv6-addr:port
endpoint without brackets surrounding the IPv6-addr will fail.

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).

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`.

/assign @kubernetes/sig-apps-api-reviews
**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.

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**

Extends deviceplugin to gracefully handle full device plugin lifecycle.
**What this PR does / why we need it**:
- Instead of using cm.capacity field to communicate device plugin resource capacity,
this PR changes to use an explicit cm.GetDevicePluginResourceCapacity() function
that returns device plugin resource capacity as well as any inactive device plugin resource.
Kubelet syncNodeStatus call this function during its periodic run to update node status
capacity and allocatable. After this call, device plugin can remove the inactive device
plugin resource from its allDevices field as the update is already pushed to API server.
- Extends device plugin checkpoint data to record registered resources
so that we can finish resource removing even upon kubelet restarts.
- Passes sourcesReady from kubelet to device plugin to avoid removing
inactive pods during grace period of kubelet restart.
- Extends gpu_device_plugin e2e_node test to verify that scheduled pods
can continue to run even after device plugin deletion and kubelet
restarts.

Updating vsphere cloud provider to support k8s cluster spread across multiple vCenters
**What this PR does / why we need it**:
vSphere cloud provider in Kubernetes 1.8 was designed to work only if all the nodes of the cluster are in one single datacenter folder. This is a hard restriction that makes the cluster not span across different folders/datacenter/vCenters. Users have use-cases to span the cluster across datacenters/vCenters.
**Which issue(s) this PR fixes**
Fixes # https://github.com/vmware/kubernetes/issues/255
**Special notes for your reviewer**:
This is a change purely in vsphere cloud provider and no changes in kubernetes core are needed.
**Release note**:
```release-note
With this change
- User should be able to create k8s cluster which spans across multiple ESXi clusters, datacenters or even vCenters.
- vSphere cloud provider (VCP) uses OS hostname and not vSphere Inventory VM Name.
That means, now VCP can handle cases where user changes VM inventory name.
- VCP can handle cases where VM migrates to other ESXi cluster or datacenter or vCenter.
The only requirement is the shared storage. VCP needs shared storage on all Node VMs.
```
