This is a hacky POC; we need to implement rootless PCM in the proper way.
Especially, pcm.Exists(existingPodName) needs to be implemented to return true
even when cgroups is not available.

This is the 2nd PR to move CSINodeInfo/CSIDriver APIs to
v1beta1 core storage APIs. It includes controller side changes.
It depends on the PR with API changes:
https://github.com/kubernetes/kubernetes/pull/73883
- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
* github.com/kubernetes/repo-infra
* k8s.io/gengo/
* k8s.io/kube-openapi/
* github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods
Change-Id: I92db545ff36fcec83afe98f550c9e630098b3135
When node lease feature is enabled, kubelet reports node status to api server
only if there is some change or it didn't report over last report interval.
Individual implementations are not yet being moved.
Fixed all dependencies which call the interface.
Fixed golint exceptions to reflect the move.
Added project info as per @dims and
https://github.com/kubernetes/kubernetes-template-project.
Added dims to the security contacts.
Fixed minor issues.
Added missing template files.
Copied ControllerClientBuilder interface to cp.
This allows us to break the only dependency on K8s/K8s.
Added TODO to ControllerClientBuilder.
Fixed GoDeps.
Factored in feedback from JustinSB.

Kubelet: only sync iptables on linux
**What this PR does / why we need it**:
Iptables is only supported on Linux, kubelet should only sync NAT rules on Linux.
Without this PR, Kubelet on Windows would logs following errors on each `syncNetworkUtil()`:
```
kubelet.err.log:4692:E0711 22:03:42.103939 2872 kubelet_network.go:102] Failed to ensure that nat chain KUBE-MARK-DROP exists: error creating chain "KUBE-MARK-DROP": executable file
```
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes#65713
**Special notes for your reviewer**:
**Release note**:
```release-note
Kubelet now only sync iptables on Linux.
```
This extends the Kubelet to create and periodically update leases in a
new kube-node-lease namespace. Based on [KEP-0009](https://github.com/kubernetes/community/blob/master/keps/sig-node/0009-node-heartbeat.md),
these leases can be used as a node health signal, and will allow us to
reduce the load caused by over-frequent node status reporting.
- add NodeLease feature gate
- add kube-node-lease system namespace for node leases
- add Kubelet option for lease duration
- add Kubelet-internal lease controller to create and update lease
- add e2e test for NodeLease feature
- modify node authorizer and node restriction admission controller
to allow Kubelets access to corresponding leases

checkLimitsForResolvConf for the pod create and update events instead of checking period
**What this PR does / why we need it**:
- Check for the same at pod create and update events instead of checking continuously for every 30 seconds.
- Increase the logging level to 4 or higher since the event is not catastrophic to cluster health .
