Automatically add node labels beta.kubernetes.io/{os,arch}
Proposal: #17981
As discussed in #22623:
> @davidopp: #9044 says cloud provider but can also cover platform stuff.
Adds a label `beta.kubernetes.io/platform` to `kubelet` that informs about the os/arch it's running on.
Makes it easy to specify `nodeSelectors` for different arches in multi-arch clusters.
```console
$ kubectl get no --show-labels
NAME STATUS AGE LABELS
127.0.0.1 Ready 1m beta.kubernetes.io/platform=linux-amd64,kubernetes.io/hostname=127.0.0.1
$ kubectl describe no
Name: 127.0.0.1
Labels: beta.kubernetes.io/platform=linux-amd64,kubernetes.io/hostname=127.0.0.1
CreationTimestamp: Thu, 31 Mar 2016 20:39:15 +0300
```

Add IPv6 address support for pods - does NOT include services
This allows a container to have an IPv6 address only and extracts the address via nsenter and iproute2 or the docker client directly. An IPv6 address is now correctly reported when describing a pod.

Add eviction-pressure-transitition-period flag to kubelet
This PR does the following:
* add the new flag to control how often a node will go out of memory pressure or disk pressure conditions see: https://github.com/kubernetes/kubernetes/pull/25282
* pass an `eviction.Config` into `kubelet` so we can group config

Use local disk for ConfigMap volume instead of tmpfs
So that ConfigMap volumes are counted against pod's storage quota.

Add an option for resource-gatherer to look only on master node
Needed for figuring out resource requirements for master components.
cc @kubernetes/sig-testing
cc @bgrant0607 - I'm changing the type of the flag in test from bool to string. I'll still handle 'true' and 'false' values, so I think this change is OK.

[e2e] kubectl stdin
Problem: Currently kubectl heavily relies on files which have to be (for lack of a better word :):):)) "written" to the file system. This hinders adoption of something like gobindata, by forcing an intermediary generated-assets directory type thing.
Solution: Lets migrate `kubectl.go` testing over to using standard input streams.

Update to support latest godep
godep v53 and earlier included all subdirs of includes in ./...
godep v54 and later only includes the exact packages required.
So all of the 'extra' packages which were subdirs but were dead code are removed.
That bit us because both codecgen and ginkgo are binaries which we got by chance in Godeps. When godep started tracking exactly what was needed instead of just grabbing entire subdirs we lost those binaries. To solve that problem godeps now have to be built with `godep save ginko codecgen ./...` so that that it explicitly pulls in those two packages. Because no one will ever remember that, I created a script in hack which lists those deps explicitly.
The better import tacking also means that it lists every single package included (transitively) in Godeps.json. Which I believe makes the godep license concatenator from @karlkfi explode in size.
But from an actual 'code that was built' PoV, and easy way to test is to see if a build with and without this PR have any difference. They should be identical.

PodWorkers UpdatePod takes options struct
First commit from https://github.com/kubernetes/kubernetes/pull/24843
Second commit:
The `PodWorkers.UpdatePod` operation is updated as follows:
* use options struct to pass arguments
* add a pod status func to allow override status
* add pod termination grace period if sync operation requires a kill pod
* add a call-back that is error aware
Third commit:
Add a `killPodNow` to kubelet that does a blocking kill pod call that properly integrates with pod workers.
The plan is to pass `killPodNow` as a function pointer into the out of resource killer.
```
// KillPodFunc kills a pod.
// The pod status is updated, and then it is killed with the specified grace period.
// This function must block until either the pod is killed or an error is encountered.
// Arguments:
// pod - the pod to kill
// status - the desired status to associate with the pod (i.e. why its killed)
// gracePeriodOverride - the grace period override to use instead of what is on the pod spec
type KillPodFunc func(pod *api.Pod, status api.PodStatus, gracePeriodOverride *int64) error
```
You can see it being used here in the WIP out of resource killer PR.

Since its hard for an individual to remember that we need codecgen and
ginkgo in godeps but don't actually have that dependancy listed in a way
that godep can automatically find.

Add utility for kubelet to log resource lists consistently
This is a simple utility for logging resource lists with standardized output.
I find it useful when logging work in node eviction, similar to kubelet logging convention for pods in same package.
