Add init containers to pods
This implements #1589 as per proposal #23666
Incorporates feedback on #1589, creates parallel structure for InitContainers and Containers, adds validation for InitContainers that requires name uniqueness, and comments on a number of implications of init containers.
This is a complete alpha implementation.

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 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

WIP v0 NVIDIA GPU support
```release-note
* Alpha support for scheduling pods on machines with NVIDIA GPUs whose kubelets use the `--experimental-nvidia-gpus` flag, using the alpha.kubernetes.io/nvidia-gpu resource
```
Implements part of #24071 for #23587
I am not familiar with the scheduler enough to know what to do with the scores. Mostly punting for now.
Missing items from the implementation plan: limitranger, rkt support, kubectl
support and docs
