apiserver: pass a listener into genericapiserver bootstrapping
**What this PR does / why we need it**:
>At the moment we pass a port via the options into the config. A zero port does not work because the loopback clients created during apiserver initialization need to know the port before. Passing a listener into the server instead would allow us to use a zero port beforehand and bootstrapping order should be fine.

Changes nvidia-gpu device plugin addon config settings:
- Runs as system critical pod
- Makes resource limits to match its resource requets
- Modifies test/e2e/scheduling/nvidia-gpus.go to cope with the recent
change of running the device plugin as a system addon.
- The resource settings of the addon is based on the test results
from 8 nvidia-tesla-k80 gpus.

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.

auth/gcp: capture stderr from gcloud config-helper
Fixes https://github.com/kubernetes/client-go/issues/327
Currently we're not capturing stderr when shelling out to "gcloud config
config-helper --format=json" fails. This patch is capturing the stderr in the
error message returned.
This gcloud command sometimes returns an upgrade reminder (in stderr) so using
`cmd.CombinedOutput()` is not an option here. Maybe we should also add an unit
test in gcp_test.go capturing this situation, too, in case someone decides to
replace this with CombinedOutput someday.

Add partial CRI container log support.
For https://github.com/kubernetes/kubernetes/issues/44976.
New CRI log format:
```
TIMESTAMP STREAM TAG CONTENT
2016-10-06T00:17:09.669794202Z stdout P log content 1
2016-10-06T00:17:09.669794203Z stdout P log content 2
```
Although unlikely, if in the future we need more metadata in each line, we could extend TAG into multiple tags splitted by `:`.

apiextensions: fix object keys in fuzzer to exclude escape characters
Jsoniter in ConfigFastest mode does not support escape characters in object keys. Hence, we have to fix this after the fuzzer chose invalid keys.
This might be only an intermediate fix if we decide to accept arbitrary object keys again. But for now, with the choice of `ConfigFastest` (f1258b01aa/feature_config.go (L66)) this change is necessary.

admission: make admission metrics compositional
Metrics emission of admission plugins and the admission chain can be implemented compositionally, i.e. completely independently from the chain logic. This PR does that, moves the whole metrics code into a sub-package to contain complexity. The plumbing logic for the emitted metrics finally is cleanly done in the apiserver bootstrapping code, instead of being totally interleaved with the core admission logic.
Ratio:
- considerably less complexity
- admission plugins are compositional, including the chain. We cannot assume that there is only one chain at the outside of the admission plugin structure. Downstream projects might have more complex admission chains, i.e. multiple chain object nested.
- addition of metrics is plumbing and should be in the apiserver plumbing code. This makes it much easier to reason about the security critical admission chain.

Enhance kubeadm `bootstrap-token`
**What this PR does / why we need it**:
This PR is part of the effort for improving kubeadm phases, and more specifically improves `bootstrap-token` phase by implementing a behaviour consistent with `kubeadm init`, that is:
- `all` subcommand
- `create` subcommand (with CA pinning stuff and --config)
- `cluster-info` subcommand was modified, removing --config (thus making it consistent with other phases)
- `allow-auto-approve` subcommand was improved, implementing also creation of RBAC rules for certificate rotation (thus making it consistent with `kubeadm init`)
- Reference docs improved
**Which issue(s) this PR fixes**
part of the effort for [#461](https://github.com/kubernetes/kubeadm/issues/461)

Hugepage resourceQuota support
**Which issue this PR fixes**
fixes#53672 ResourceQuota part
**Special notes for your reviewer**:
What I'm concerned most is the change in quota evaluator:
Rather than add check especially for resource hugage, I would prefer add a check list, that could be easily extended by adding corresponding prefix into the list (As far as I know, pluginResources will also support ResourceQuota in later versions)

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.
```
Internally tested and reviewed the code.
