Add support for PersistentVolumeClaim in Attacher/Detacher interface
The attach detach interface does not support volumes which are referenced through PVCs. This PR adds that support
This patch adds the --exit-on-lock-contention flag, which must be used
in conjunction with the --lock-file flag. When provided, it causes the
kubelet to wait for inotify events for that lock file. When an 'open'
event is received, the kubelet will exit.

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

Kubelet eviction flag parsers and tests
The first two commits are from https://github.com/kubernetes/kubernetes/pull/24559 that have achieved LGTM.
The last commit is only part that is interesting, it adds the parsing logic to handle the flags, and reserves `pkg/kubelet/eviction` for eviction manager logic.

Unit test for negative value of allocatable resources
Introduce unit test for checking resource quantities for kubelet's allocatable resources.
Covered values:
* negative quantity value: error expected
* invalid quantity unit: error expected
* valid quantity: error not expected
Running go test with -v, returned error are logged as well for more information:
```shell
=== RUN TestValueOfAllocatableResources
--- PASS: TestValueOfAllocatableResources (0.00s)
server_test.go:47: Returned err: "resource quantity for \"memory\" cannot be negative: -150G"
server_test.go:47: Returned err: "unable to parse quantity's suffix"
PASS
ok k8s.io/kubernetes/cmd/kubelet/app 0.020s

Move typed clients into clientset folder
Move typed clients from `pkg/client/typed/` to `pkg/client/clientset_generated/${clientset_name}/typed`.
The first commit changes the client-gen, the last commit updates the doc, other commits are just moving things around.

rkt: bump rkt version to 1.2.1
Upon bumping the rkt version, `--hostname` is supported. Also we now gets the configs from the rkt api service, so `stage1-image` is deprecated.

Make kubelet use an arch-specific pause image depending on GOARCH
Related to: #22876, #22683 and #15140
@ixdy @pwittrock @brendandburns @mikedanese @yujuhong @thockin @zmerlynn
When setting kube/system-resources for a node, negative quantities can result in
node's allocatable being higher then node's capacity.
Let's check the quantity and return error if it is negative.
