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

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.

/cc @vishh @yujuhong @pmorie 

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.

Resource name constants were incorrect in versioned types.go

The constant field names and actual values to quota requests and limits for cpu and memory were incorrect in the v1 types.go file.

Important to note for reviewer:
* the constant fields here are unused in the project at this time
* the values those unused constant fields mapped to are not actually supported by the project
* there is no backwards compatibility concern, but if/when we look to convert to using versioned clients, we should have the correct constant fields and values.

The correct values were here:

Reduce allocations during conversion, enable new UnsafeConvertToVersion path

Cleans up the conversion path to avoid a few unnecessary allocations, then creates a new UnsafeConvertToVersion path that will allow encode/decode to bypass copying the object for performance. In that subsequent PR, ConvertToVersion will start to call Copy() and we will refactor conversions to reuse as much of the existing object as possible.

Also changes the unversioned.ObjectKind signature to not require allocations - speeds up a few common paths.
