@aveshagarwal - this PR just uses library functions from previous one.
@kevin-wangzefeng - the only thing that's left is to write an admission controller. I don't remember what was the agreements. Are you going to write it, or should I?

hack/verify-staging-client-go.sh: use git-archive to survive dirty working tree
We used rsync before and copied over the checkout. If some other script, created or changed files, godep refused to run.
Now the script uses git-archive against HEAD instead.

move kube-dns to a separate service account
Switches the kubedns addon to run as a separate service account so that we can subdivide RBAC permission for it. The RBAC permissions will need a little more refinement which I'm expecting to find in https://github.com/kubernetes/kubernetes/pull/38626 .
@cjcullen @kubernetes/sig-auth since this is directly related to enabling RBAC with subdivided permissions
@thockin @kubernetes/sig-network since this directly affects now kubedns is added.
```release-note
`kube-dns` now runs using a separate `system:serviceaccount:kube-system:kube-dns` service account which is automatically bound to the correct RBAC permissions.

kube-apiserver: add a bootstrap token authenticator for TLS bootstrapping
Follows up on https://github.com/kubernetes/kubernetes/pull/36101
Still needs:
* More tests.
* To be hooked up to the API server.
- Do I have to do that in a separate PR after k8s.io/apiserver is synced?
* Docs (kubernetes.io PR).
* Figure out caching strategy.
* Release notes.
cc @kubernetes/sig-auth-api-reviews @liggitt @luxas @jbeda
```release-notes
Added a new secret type "bootstrap.kubernetes.io/token" for dynamically creating TLS bootstrapping bearer tokens.

add godep manifest files to staging repos
The staging repos should have manifests that match the godeps of kube so we know what they build against. We don't need the actual vendored code, since a sync script on the other side needs to find the correct level of other staging directories and thus requires its own `godep restore && go get && godep save` cycle.
@sttts ptal
@lavalamp @caesarxuchao client-go needs a lot of unwinding to do something similar, but the idea is that you can run an acyclic path to get this updated by copying the types and dependencies with `go list`, then generate the clients, then generate this manifest. Then in your sync script you can pull the proper levels and finish the actual vendoring.

ResourceQuota ability to support default limited resources
Add support for the ability to configure the quota system to identify specific resources that are limited by default. A limited resource means its consumption is denied absent a covering quota. This is in contrast to the current behavior where consumption is unlimited absent a covering quota. Intended use case is to allow operators to restrict consumption of high-cost resources by default.
Example configuration:
**admission-control-config-file.yaml**
```
apiVersion: apiserver.k8s.io/v1alpha1
kind: AdmissionConfiguration
plugins:
- name: "ResourceQuota"
configuration:
apiVersion: resourcequota.admission.k8s.io/v1alpha1
kind: Configuration
limitedResources:
- resource: pods
matchContains:
- pods
- requests.cpu
- resource: persistentvolumeclaims
matchContains:
- .storageclass.storage.k8s.io/requests.storage
```
In the above configuration, if a namespace lacked a quota for any of the following:
* cpu
* any pvc associated with particular storage class
The attempt to consume the resource is denied with a message stating the user has insufficient quota for the matching resources.
```
$ kubectl create -f pvc-gold.yaml
Error from server: error when creating "pvc-gold.yaml": insufficient quota to consume: gold.storageclass.storage.k8s.io/requests.storage
$ kubectl create quota quota --hard=gold.storageclass.storage.k8s.io/requests.storage=10Gi
$ kubectl create -f pvc-gold.yaml
... created

kubeadm: Make a separate util package for kubeconfig logic
**What this PR does / why we need it**:
There are a lot of packages that need to consume kubeconfig logic, so it should be in a central place.
Having it in `kubeadmutil` is suboptimal, because then it get mixed with everything else.
This splits that logic out to a generic place so it then also can be consumed in https://github.com/kubernetes/kubernetes/pull/41417, from where it's broken out.
- Move {admin,kubelet}.conf out as constants
- Make a separate util package for kubeconfig logic

Added a basic monitor for providing etcd version related info
Fixes#41071
This tool scrapes metrics partly from etcd's /version and /metrics endpoints and partly using etcdctl and exposes them as prometheus metrics at `http://localhost:9101/metrics` endpoint on the master. Here is a summary of the metrics it exposes (self-explanatory from the code):
- etcdVersionFetchCount = prometheus.NewCounterVec(
prometheus.CounterOpts{
Namespace: "etcd",
Name: "version_info_fetch_count",
Help: "Number of times etcd's version info was fetched, labeled by etcd's server binary and cluster version",
},
[]string{"serverversion", "clusterversion"})
- etcdGRPCRequestsTotal = prometheus.NewCounterVec(
prometheus.CounterOpts{
Namespace: namespace,
Name: "grpc_requests_total",
Help: "Counter of received grpc requests, labeled by grpc method and grpc service names",
},
[]string{"grpc_method", "grpc_service"})
For further info on how to run this as a binary/docker-container/kubernetes-pod and checking the metrics, have a look at the README.md file.

Adds functionality to look at the components of the GOPATH looking for
the gazel executable, rather than treating the GOPATH as if it was a
single directory.
