add "admission" API group
This commit is an initial pass at providing an admission API group.
The API group is required by the webhook admission controller being
developed as part of https://github.com/kubernetes/community/pull/132
and could be used more as that proposal comes to fruition.
**Note:** This PR was created by following the [Adding an API Group](https://github.com/kubernetes/community/blob/master/contributors/devel/adding-an-APIGroup.md) documentation.

From https://github.com/kubernetes/kubernetes/issues/45991#issuecomment-302292404.
Don't redefine `pods` so we can return real pod names instead of empty array.

Fix kuberuntime GetPods.
The `ImageID` is not populated from `GetPods` in kuberuntime.
Image garbage collector is using this field, https://github.com/kubernetes/kubernetes/blob/master/pkg/kubelet/images/image_gc_manager.go#L204.
Without this fix, image garbage collector will try to garbage collect all images every time. Because docker will not allow that, it should be fine. However, I'm not sure whether the unnecessary remove will cause any problem, e.g. overload docker image management system and make docker hang.
@dchen1107 @yujuhong @feiskyer Do you think we should cherry-pick this?

This patch adds instructions for how to run the in-cluster client-go example.
To make this example executable, providing a Dockerfile and build steps so
that it can directly be run on minikube.
This is part of the body of work improving the client library samples.

Two new behaviors are tested:
1. The output message that deprecatedAlias gives when it is called must
include the word "deprecatated" and the name of the new function
that the user should use instead.
2. The correct function must be called by the alias (alias should "fall
back" to the functionality of the original.

Fix serialization of EnforceNodeAllocatable
EnforceNodeAllocatable being `nil` and `[]` are treated in different
ways by kubelet. Namely, `nil` is replaced with `[]string{"pods"}` by
the defaulting mechanism.
E.g. if you run kubelet in Docker-in-Docker environment
you may need to run it with the following options:
`--cgroups-per-qos=false --enforce-node-allocatable=`
(this corresponds to EnforceNodeAllocatable being empty array and not
null) If you then grab kubelet configuration via /configz and try to
reuse it for dynamic kubelet config, kubelet will think that
EnforceNodeAllocatable is null, failing to run in the
Docker-in-Docker environment.
Encountered this while updating Virtlet for Kubernetes 1.6
(the dev environment is based on kubeadm-dind-cluster)

kube-proxy: add --write-config-to flag
Add --write-config-to flag to kube-proxy to write the default configuration
values to the specified file location.
@deads2k suggested I create my own scheme for this, so I followed the example he shared with me. The only bit currently still referring to `api.Scheme` is where we create the event broadcaster recorder. In order to use the custom private scheme, I either have to pass it in to `NewProxyServer()`, or I have to make `NewProxyServer()` a member of the `Options` struct. If the former, then I probably need to export `Options.scheme`. Thoughts?

Use integer comparisons instead of string comparisons in autoscaler config validation
**What this PR does / why we need it**:
kube-up.sh doesn't work if MAX_INSTANCES_PER_MIG is specified and KUBE_AUTOSCALER_MAX_NODES is lexicographically smaller ("10" < "2").
