- 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
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.
Adding blank line between comment tag and package name in doc.go. So
that the comment tags such as '+k8s:deepcopy-gen=package' do not show up
in GoDoc.

CSI: skip attach for non-attachable drivers
**What this PR does / why we need it**:
This is implementation of https://github.com/kubernetes/community/pull/2523. CSI volumes that don't need attach/detach now don't need external attacher running.
WIP:
* contains #67803 to get CSIDriver API. Ignore the first commit.

Allow ImageReview backend to add audit annotations.
**What this PR does / why we need it**:
This can be used to create annotations that will allow auditing of the created
pods.
The change also introduces "fail open" audit annotations in addition to the
previously existing pod annotation for fail open. The pod annotations for
fail open will be deprecated soon.

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
This can be used to create annotations that will allow auditing of the created
pods.
The change also introduces "fail open" audit annotations in addition to the
previously existing pod annotation for fail open. The pod annotations for
fail open will be deprecated soon.

Changed admission controller to allow volume expansion for all volume plugins
**What this PR does / why we need it**:
There are two motivations for this change:
1. CSI plugins are soon going to support volume expansion. For such plugins, admission controller doesn't know whether the plugins are capabale of supporting volume expansion or not.
2. Currently, admission controller rejects PVC updates for in-tree plugins that don't support volume expansion (e.g., NFS, iSCSI). This change allows external controllers to expand volumes similar to how external provisioners are accommodated.
**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 #
**Special notes for your reviewer**:
This PR mimics the behavior of the PV controller when PVs are provisioned externally by logging and setting a new event for PVs that are being expanded externally. As SIG Storage is planning new types of operations on PVs, it may make more sense to a have a single event for all actions taken by external controllers.
**Release note**:
```release-note
The check for unsupported plugins during volume resize has been moved from the admission controller to the two controllers that handle volume resize.
```

under unbrella: #66680
We start with injecting external informer/lister into node admission controller for that it's slightly simpler than the others.
Here is the thing I actually did in this pull:
1. Enable plugin initializer to inject external/internal clientset/informers into the admission controllers.
2. Receive external informer in node admission controller.
3. Create a `AdmissionConfig` following how we did in `AuthenticationConfig` and `AuthorizationConfig` and creates the actual plugin initializers and the admission post-start hook in its `New()` method
Make apiserver pass connectRequest.Options directly to the admission layer. All
the information in rest.ConnectRequest is present in admission attributes.

Add availability zones support to Azure managed disks
**What this PR does / why we need it**:
Continue of [Azure Availability Zone feature](https://github.com/kubernetes/features/issues/586).
This PR adds availability zone support for Azure managed disks and its storage class. Zoned managed disks is enabled by default if there are zoned nodes in the cluster.
The zone could also be customized by `zone` or `zones` parameter, e.g.
```yaml
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
annotations:
name: managed-disk-zone-1
parameters:
zone: "southeastasia-1"
# zones: "southeastasia-1,"southeastasia-2"
cachingmode: None
kind: Managed
storageaccounttype: Standard_LRS
provisioner: kubernetes.io/azure-disk
reclaimPolicy: Delete
volumeBindingMode: Immediate
```
All zoned AzureDisk PV will also be labeled with its availability zone, e.g.
```sh
$ kubectl get pvc pvc-azuredisk-az-1
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
pvc-azuredisk-az-1 Bound pvc-5ad0c7b8-8f0b-11e8-94f2-000d3a07de8c 5Gi RWO managed-disk-zone-1 2h
$ kubectl get pv pvc-5ad0c7b8-8f0b-11e8-94f2-000d3a07de8c --show-labels
NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE LABELS

aggregate admin from edit and view to ensure coverage
ClusterRole aggregate has worked quite well. This updates the edit role to be aggregated from a separate edit and view and updates the admin role to aggregated from admin, edit, and view. This ensures coverage (we previously had unit tests, but that didn't work as people aggregated more powers in) and it makes each role smaller since it only has a diff to consider.

```release-note
admin RBAC role now aggregates edit and view. edit RBAC role now aggregates view.
